Sen. Cynthia Lummis

Senator for Wyoming

pronounced SIN-thee-uh // LUH-miss


Lummis is the junior senator from Wyoming and is a Republican. She has served since Jan 3, 2021. Lummis is next up for reelection in 2026 and serves until Jan 3, 2027.

She was previously the representative for Wyoming’s at-large district as a Republican from 2009 to 2016.

Lummis is among the Republican legislators who participated in the months-long, multifarious attempted coup following the 2020 presidential election. In the days leading up to January 6, Lummis had announced her intent to object on that day to the inclusion of some states in the final tally that determined the next president, which would have disenfranchised millions of voters based on lies, conspiracy theories, and preposterous legal theories all falsely claiming various sorts of mass fraud that did not occur. The announcement amplified the message that inspired the Jan. 6 insurrection at the Capitol. On January 6, 2021 in the hours after the insurrection at the Capitol, Lummis voted to reject the state-certified election results of Arizona and/or Pennsylvania (states narrowly won by Democrats), which could have changed the outcome of the election. These legislators have generally changed their story after their vote, claiming it was merely a protest and not intended to change the outcome of the election as they clearly sought prior to the vote. The January 6, 2021 insurrection at the Capitol disrupted Congress’s count of electors that determined the outcome of the presidential election with the goal to prevent President Joe Biden from taking office.

Does 2 not sound like a lot? Very few bills are ever enacted — most legislators sponsor only a handful that are signed into law. But there are other legislative activities that we don’t track that are also important, including offering amendments, committee work and oversight of the other branches, and constituent services.

We consider a bill enacted if one of the following is true: a) it is enacted itself, b) it has a companion bill in the other chamber (as identified by Congress) which was enacted, or c) if at least about half of its provisions were incorporated into bills that were enacted (as determined by an automated text analysis, applicable beginning with bills in the 110th Congress).

We don’t track why legislators miss votes, but it’s often due to medical absenses and major life events.
