Voting analysis

Mark Warner is vice chairman of the Senate intelligence committee, and his defections run toward the Republican position on specific bills rather than away from his caucus's compromises — the opposite direction from most Democrats who appear this high in the ranking.

Backing a bill through every stage

On one measure he supported cloture, an adopted amendment, cloture on that amendment, and final passage — the complete sequence, each time against most of his caucus. He also voted for passage of a separate bill on the same terms. Where other Democratic defectors are recorded voting no against their own side's deals, Warner is recorded voting yes alongside Republicans.
