Alfred Vellucci and Francis Duehay

They took opposite sides on 80 of the 229 contested roll calls they both voted on, and the same side on 149.

Contested means the roll carried at least one nay. Across every shared roll call, unanimous ones included, they agreed on 1,700 of 1,780. 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.
