Sen. Cynthia Lummis

Senator for Wyoming


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, by calling for entire states to be disenfranchised in the 2020 presidential election, fomented the terrorist attack on the Capitol on January 6, 2021 that aimed to prevent the determination of the next president of the United States. 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 count of electors that determines the next president, disenfranchising 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 attack on the Capitol. On January 6, 2021 in the hours after the attack on the Capitol, Lummis voted for the exclusion of Arizona and/or Pennsylvania — states narrowly won by Democrats — from the count of Electoral College votes that determined the next President of the United States.

Does 1 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).
