Rep. Ken Buck

Representative for Colorado’s 4th District

pronounced ken // buk


Buck is the representative for Colorado’s 4th congressional district (view map) and is a Republican. He has served since Jan 6, 2015. Buck is next up for reelection in 2022 and serves until Jan 3, 2023.

Buck 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. Shortly after the 2020 election, Buck joined a case before the Supreme Court calling for all the votes for president in Georgia, Michigan, Pennsylvania, and Wisconsin — states that were narrowly won by Democrats — to be discounted, claiming that some voters there followed procedures set by the wrong state officials. The case amplified lies and conspiracy theories that fueled the movement that led to the attack on the Capitol. The Supreme Court rejected the case. Following the rejection of several cases before the Supreme Court, one legislator called for violence.

Does 3 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).
