I don't think a lot of people know this. "Yes" votes are "given out" by party leaders as favors to to those who are willing to play ball so that they can please the folks back home when the outcome of the issue is already assured. When a candidate makes a big deal during a campaign about how they voted against the grain on a particularity thorny issue that pleased a lot of voters in their district, take it with a huge grain of salt and a hard look at their broader voting record.
