Congressional Voting Statistics at a Glance
Congressional voting statistics are easiest to read when you separate voting rules from voting volume. The Senate’s procedures create a layered system: some actions need only a simple majority, while others require supermajority thresholds that materially change what can pass and when.
This article pulls the supplied data into one place so you can see the main Senate voting rules, the scale of cloture activity across recent Congresses, the busiest vote-arama moments, and a set of historical vote totals for individual senators.

Fast Facts
Big number: The Robert C. Byrd total of 18,689 Senate votes is the highest figure in the supplied senator list (Senators Who Have Cast More than 10,000 Votes).
Procedural anchor: Under Senate debate rules, three-fifths of those duly chosen and sworn are needed to invoke cloture on legislation (Senate About Voting).
Recent clustering: The 2025-06-30 vote-arama had 43 roll-call votes (Senate Vote-aramas).
Volume snapshot: The 119th Congress had 253 cloture motions filed and 253 votes on cloture in 2025-2026, with 211 cloture motions invoked (Senate Action on Cloture Motions).
At a glance
- A simple majority is enough for most Senate measures (Senate About Voting).
- A tie can be broken by the vice president (Senate About Voting).
- Some outcomes require two-thirds of the Senate, including expulsion, veto override, treaty consent, constitutional amendment proposals, and conviction after impeachment (Senate About Voting).
- Voice votes do not record names or vote tallies, while division votes are used to count yea and no after a voice vote outcome (Senate About Voting).
- Roll-call votes are available online from the 101st Congress onward (Senate About Voting).
How Senate Voting Thresholds Work
The most useful way to read congressional voting statistics is to start with the rule, not the raw count. The Senate does not use one universal threshold for every action, and that is the main reason a vote total can mean very different things depending on the context.
The baseline voting rule
For most measures, the Senate uses a simple majority requirement (Senate About Voting). That sounds straightforward, but in practice it sits beside a long list of exceptions that raise the bar.
The supplied data identifies several important supermajority cases:
- Two-thirds Senate vote to expel a senator (Senate About Voting)
- Two-thirds Senate vote to override a presidential veto (Senate About Voting)
- Two-thirds Senate vote to propose a constitutional amendment for ratification by the states (Senate About Voting)
- Two-thirds Senate vote to convict an impeached official (Senate About Voting)
- Two-thirds Senate vote to consent to ratification of a treaty (Senate About Voting)
- Three-fifths of those duly chosen and sworn to invoke cloture on legislation (Senate About Voting)
- Two-thirds vote to invoke cloture on a measure that would amend the Senate’s rules (Senate About Voting)
That mix matters because it explains why procedural statistics can become more important than the final vote itself. If cloture is hard to invoke, the Senate may spend substantial time voting on whether to move forward at all.
Key procedural categories
The dataset also points to several procedural mechanics that shape how votes are counted and recorded:
- One-fifth of a quorum of senators can request a roll-call vote (Senate About Voting).
- Voice votes do not record names or tallies (Senate About Voting).
- Division votes are used to count senators voting yea and no when verifying a voice vote outcome (Senate About Voting).
- Much of Senate business is handled by unanimous consent, where a measure passes if no senator objects (Senate About Voting).
These are not just trivia details. They define which actions become part of the visible vote record and which ones do not.
Quick comparison table
| Action or rule | Required threshold | Source label |
|---|---|---|
| Most Senate measures | Simple majority | Senate About Voting |
| Tie vote | Vice president may break the tie | Senate About Voting |
| Cloture on legislation | Three-fifths of those duly chosen and sworn | Senate About Voting |
| Cloture on a measure changing Senate rules | Two-thirds vote | Senate About Voting |
| Expel a senator | Two-thirds vote | Senate About Voting |
| Override a presidential veto | Two-thirds vote | Senate About Voting |
| Propose a constitutional amendment | Two-thirds vote | Senate About Voting |
| Convict an impeached official | Two-thirds vote | Senate About Voting |
| Consent to ratify a treaty | Two-thirds vote | Senate About Voting |
This table is the cleanest way to see that “Senate voting” is not one statistic but a set of overlapping decision rules.
Vote-Aramas and Clustered Roll-Call Voting
The term vote-arama is useful because it captures a specific kind of voting burst: many back-to-back roll-call votes in a compressed period. The dataset shows both the term’s history and several recent high-volume examples.
What the data says about vote-aramas
- The Senate has held as many as 44 votes in a row in a vote-arama (Senate Vote-aramas).
- The term vote-arama gained public recognition in 1996 (Senate Vote-aramas).
- The process developed under the Congressional Budget Act of 1974 (Senate Vote-aramas).
- Senate staff anecdotal evidence suggests the term may have been used as early as 1992 (Senate Vote-aramas).
The history here shows two separate ideas. First, the procedure is old enough to be embedded in Senate operations. Second, the label itself became more widely recognized later.
Recent vote-arama counts
| Date | Roll-call votes | Source label |
|---|---|---|
| 2026-04-22 | 17 | Senate Vote-aramas |
| 2025-07-16 | 19 | Senate Vote-aramas |
| 2025-06-30 | 43 | Senate Vote-aramas |

| 2015-03-26 | 43 | Senate Vote-aramas |
| 2013-03-22 | 43 | Senate Vote-aramas |
What stands out in the vote-arama data
Three patterns are visible right away:
- The upper end is high. A vote-arama can reach 43 or 44 votes in a row (Senate Vote-aramas).
- The range is wide. The supplied examples run from 17 to 43 roll-call votes (Senate Vote-aramas).
- The clustering is not limited to one era. The data includes examples from 2013, 2015, 2017, 2021, 2022, 2025, and 2026 (Senate Vote-aramas).
That makes vote-arama a recurring procedural feature, not a one-off event.
Why clustered votes matter
When multiple roll-call votes stack up in a short period, the Senate’s workload becomes visible in a different way. A single vote can tell you whether a motion passed. A sequence of votes can tell you how much floor time a procedural fight is consuming.
The supplied counts show that some vote-aramas are relatively compact, such as 17 or 19 roll-call votes, while others stretch into the low-to-mid 40s (Senate Vote-aramas). That spread is useful because it gives readers a sense of the procedural intensity without requiring a broader narrative.
Cloture Motion Statistics by Congress
If you want one of the clearest volume indicators in the dataset, it is the cloture-motion series. Cloture statistics show how often senators tried to end debate, how often cloture was voted on, and how often it was invoked.
Latest Congress in the dataset
The 119th Congress posted these figures in 2025-2026 (Senate Action on Cloture Motions):
- 253 cloture motions filed
- 253 votes on cloture
- 211 cloture motions invoked
That alignment between motions filed and votes on cloture is notable because it suggests the procedural sequence was fully carried through in the available data for that Congress (Senate Action on Cloture Motions).
Comparison across recent Congresses
| Congress | Filed | Votes on cloture | Invoked | Source label |
|---|---|---|---|---|
| 119th (2025-2026) | 253 | 253 | 211 | Senate Action on Cloture Motions |
| 118th (2023-2024) | 266 | 241 | 227 | Senate Action on Cloture Motions |
| 117th (2021-2022) | 336 | 289 | 270 | Senate Action on Cloture Motions |
| 116th (2019-2020) | 328 | 298 | 270 | Senate Action on Cloture Motions |
| 115th (2017-2018) | 201 | 168 | 157 | Senate Action on Cloture Motions |
Reading the table
Several simple comparisons stand out:
- The 117th Congress had the largest number of cloture motions filed in this set at 336 (Senate Action on Cloture Motions).
- The 116th Congress was close behind with 328 filed and 298 votes on cloture (Senate Action on Cloture Motions).
- The 115th Congress is the lowest in the list, with 201 filed, 168 votes on cloture, and 157 invoked (Senate Action on Cloture Motions).
- The 119th Congress shows 253 filed and 211 invoked, which places it below the peak levels in the 116th and 117th Congresses but above the 115th Congress on every listed measure (Senate Action on Cloture Motions).
What cloture figures can tell you
Cloture is a procedure-focused statistic, so its value comes from pattern recognition rather than a single dramatic number. From the supplied data, you can see that:
- Cloture activity remained high across multiple Congresses.
- The counts change meaningfully from one Congress to another.
- The difference between motions filed, votes on cloture, and motions invoked gives a more precise picture than any one of the three figures alone.
The series also helps explain why Senate voting statistics often need context. A raw vote count without procedural context can understate how much work is happening on the floor.
Senators with More Than 10,000 Votes
Another useful slice of congressional voting statistics is personal vote totals. These figures show how many times individual senators were recorded in the vote system over long careers.
Named senators in the supplied data
| Senator | Senate votes cast | Source label |
|---|---|---|
| Robert C. Byrd | 18,689 | Senators Who Have Cast More than 10,000 Votes |
| Chuck Grassley | 15,153 | Senators Who Have Cast More than 10,000 Votes |
| Orrin G. Hatch | 14,554 | Senators Who Have Cast More than 10,000 Votes |
| Ernest F. Hollings | 14,193 | Senators Who Have Cast More than 10,000 Votes |
| Pete V. Domenici | 13,666 | Senators Who Have Cast More than 10,000 Votes |
| Thad Cochran | 13,173 | Senators Who Have Cast More than 10,000 Votes |
| Joe Biden | 12,810 | Senators Who Have Cast More than 10,000 Votes |
| Max S. Baucus | 12,176 | Senators Who Have Cast More than 10,000 Votes |
| Quentin N. Burdick | 11,925 | Senators Who Have Cast More than 10,000 Votes |
| Jesse Helms | 11,753 | Senators Who Have Cast More than 10,000 Votes |
| Robert J. Dole | 11,486 | Senators Who Have Cast More than 10,000 Votes |
| Mark O. Hatfield | 11,245 | Senators Who Have Cast More than 10,000 Votes |
What the personal totals show
The spread among these senators is wide even though every name is above 10,000 votes (Senators Who Have Cast More than 10,000 Votes). The highest figure, 18,689, is far above the lower end of the group at 11,245.
That matters for two reasons:
- It shows how long-serving senators can accumulate very large recorded vote totals.
- It offers a simple way to compare legislative longevity through a voting lens rather than a biography lens.
Highest totals in the list
The top tier in the supplied figures is especially concentrated:
- Robert C. Byrd - 18,689 votes (Senators Who Have Cast More than 10,000 Votes)
- Chuck Grassley - 15,153 votes (Senators Who Have Cast More than 10,000 Votes)
- Orrin G. Hatch - 14,554 votes (Senators Who Have Cast More than 10,000 Votes)
- Ernest F. Hollings - 14,193 votes (Senators Who Have Cast More than 10,000 Votes)
The gap between the top entry and the rest of the list is substantial, which makes the leading figure stand out even without any additional context.
A simple way to read the list
You can think about these totals in layers:
- 18,000-plus: an outlier level in the provided set
- 15,000 to 14,000 range: a dense high-vote cluster
- 13,000 to 12,000 range: still very high but more compressed
- 11,000 range: the lower end of the included list, still well above the threshold for inclusion (Senators Who Have Cast More than 10,000 Votes)
That structure makes the list more useful than a flat roster of names. It shows the distribution of vote totals instead of just the names themselves.
What These Congressional Voting Statistics Show
Taken together, the dataset shows that congressional voting statistics are really three different stories at once.
First, they show rules. The Senate uses simple majority voting in most cases, but important exceptions require two-thirds or three-fifths thresholds (Senate About Voting).
Second, they show procedural intensity. Vote-aramas and cloture-motion totals reveal that voting can bunch into extended bursts, with some recent examples reaching 43 or 44 roll-call votes in a row and recent Congresses recording hundreds of cloture motions (Senate Vote-aramas; Senate Action on Cloture Motions).
Third, they show career-scale participation. Individual senators in the supplied list crossed 10,000 votes by a wide margin, with the top entry reaching 18,689 Senate votes (Senators Who Have Cast More than 10,000 Votes).
Key patterns worth remembering
- Senate voting is rule-dependent, not one-size-fits-all.
- Cloture data is one of the best ways to measure procedural pressure.
- Vote-aramas provide a snapshot of how dense floor action can become.
- Long-serving senators accumulate vote totals that can be compared directly.
- The official record becomes more readable when you separate thresholds, volume, and individual participation into distinct groups.
Fast facts to reuse
- Simple majority is the default Senate standard for most measures (Senate About Voting).
- Two-thirds appears repeatedly for the Senate’s most consequential actions, including veto override and treaty consent (Senate About Voting).
- Three-fifths is the cloture threshold on legislation (Senate About Voting).
- The strongest vote-arama figure in the supplied set is 44 votes in a row (Senate Vote-aramas).
- The highest cloture-motion count in the Congress comparison is 336 filed in the 117th Congress (Senate Action on Cloture Motions).
- The highest named senator total in the vote list is 18,689 for Robert C. Byrd (Senators Who Have Cast More than 10,000 Votes).
