How these are counted
Each roll call takes the policy area the Library of Congress gave the bill it is about; a vote on an amendment counts under its bill. 468 of the House’s 676 roll calls this Congress have an issue. Left out as procedural (208): votes on House rules and the previous question, motions to recommit or adjourn, quorum calls and the Speaker election. “With the Democratic majority” counts every issue vote on which most Democrats voted the same way, Yea or Nay. “Against both parties” = most Democrats and most Republicans voted one way and this member the other. “With the Republican majority” = a party-line vote (most of each party on opposite sides) on which this member sided with the Republicans. Independents count with the party they caucus with.
