Method and data

Method. Democrats with a nominate_dim1 score above the lowest Republican score in the same chamber and Congress, divided by Democrats scored. One member at the edge sets the threshold; the pairwise share in the text uses every member. House counts include Delegates and the Resident Commissioner, and the tested removals of those rows and of members with 13 or fewer votes leave every tested count unchanged. Senate Democrats are party code 100 only; counting independents as Democrats raises the Senate count by one in the 92nd through 97th Congresses and leaves the zeros since 2005 unchanged.
