Francis Duehay and Walter Sullivan

They took opposite sides on 158 of the 269 contested roll calls they both voted on, and the same side on 111.

Contested means the roll carried at least one nay. Across every shared roll call, unanimous ones included, they agreed on 2,090 of 2,248. Each disagreement below links to the record it came from, so the figure above can be checked rather than taken on trust. Where this comes from.
