Just like the rules governing debate, there are rules for the voting process.
- Motions in the chamber, besides final action on bills, can be decided by a voice vote. A voice vote is what it sounds like - the yays say yay, then the nays say nay. Individual votes are not counted. If the voice vote is close, it's called again. If it's still uncertain if there are more yays or nays, then the votes are counted individually.
- Final action, however, must be counted by a roll call vote. (The voting decision of each member is recorded). Every member present in the House and Senate must vote. When represenatives or senators do not want to vote, they have to step out of the room during voting.
