Members’ “likelihood of agreement” scores on each vote are calculated using a regression for which the input is Trump’s 2016 vote margin in every member’s state or district and the output is the probability that a member will vote for the bill. The plus-minus on each vote is the difference between the member’s vote (100 percent for a “yes,” 0 percent for a “no”) and the likelihood of agreement. Averages do not include missed votes.
