PACs and January 6th: Campaign finance and objections to the Electoral College vote count

Are members of Congress who receive more of their campaign funding from organized interests more supportive of democratic norms compared to members who receive more of their contributions from individual donors? We analyze the campaign receipts of Republican House members in the 2020 campaign cycle and votes to object to electors for Joe Biden from Arizona and Pennsylvania and find that greater contributions to members’ campaigns from business PACs are associated with a lower probability that members voted to object to electors. Further, members’ own margin of victory in 2020 has no association with these votes when controlling for other factors, but members from districts where Trump performed better are more likely to have objected to counting Electoral College votes for his opponent. Our results demonstrate a positive association between campaign contributions from corporate PACs and support for democratic institutions within the Republican caucus in the U.S. House.
