Constituents vs. funders
Voted the way most of their constituents wanted on 1 of 1 key votes (100%)
None of these votes set their $10K+ industry funders against a clear majority of their constituents. Constituent views come from the Cooperative Election Study, a survey of about 60,000 adults a year. A side counts as what constituents wanted only when it leads by more than the margin of error; closer results are shown as split. Party explains most votes, and none of this shows that money changed a vote.
