Constituents vs. funders
Voted the way most of their constituents wanted on 5 of 5 key votes (100%)
On 2 votes, industries that gave them $10K+ before the vote wanted the opposite of what most of their constituents wanted. They sided with the funders 0 times and with their constituents 2. 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.
