Replication Data for: House Republican Decision-Making Following the Capitol Riot

Donald Trump’s unsubstantiated vote fraud claims following the 2020 election divided the Republican Party. Numerous Republicans supported Trump’s efforts to overturn the election, while others did not. These futile attempts reached a boiling point during the January 6th attack on the United States Capitol. Even in the wake of such violence, many House Republicans continued to amplify Trump’s baseless claims by voting to exclude the election results from Arizona and Pennsylvania. We analyze these roll call votes to determine likely motivations for why some House Republicans were still willing to support Donald Trump’s position following the Capitol riot. We then replicate our analysis with the January 13th impeachment and May 19th vote to establish a Bipartisan January 6th Commission to investigate the insurrection. Our findings indicate the relevance of constituent preferences, Donald Trump’s popularity, legislator ideology, and the racial diversity of the constituents represented by Republicans.
