Alfred Vellucci and Walter Sullivan

They took opposite sides on 89 of the 228 contested roll calls they both voted on, and the same side on 139.

Contested means the roll carried at least one nay. Across every shared roll call, unanimous ones included, they agreed on 1,506 of 1,595. 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.
