Elections must be decided by counting votes

Our work to hold Congress accountable only matters if elections are decided by counting votes. President Trump, his senior government advisors, and Republican legislators collaborated to have the 2020 presidential election decided instead by incumbent politicians running in the very same election. Their attempts to suppress entire state-certified vote counts without adjudication in the courts and using a disinformation campaign of lies and conspiracy theories was a months-long, multifarious attempted coup.

Lummis was among the Republican legislators who participated in the attempted coup. Lummis was a part of a coordinated campaign with the Trump Administration spreading conspiracy theories about the election. In the days leading up to January 6, 2021’s congressional certification of the election, Lummis announced her intent to object to the inclusion of some states from the certification, which would have disenfranchised millions of voters and amplified lies, conspiracy theories, and preposterous legal theories about purported fraud. On January 6, 2021 in the hours after the violent 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 violent insurrection at the Capitol, led on the front lines by militant white supremacy groups, attempted to prevent President-elect Joe Biden from taking office by disrupting Congress’s count of electors.

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).
