It's usually easy to predict how particular California state legislators will vote on a bill: 99 percent of the time, Democrats vote the same way as the majority of their party; 94 percent of the time, Republicans vote the same way as the majority of their party, according to a Bee review of voting records from the 2011-2012 legislative session.

The two parties are each unanimous in their support or rejection of a bill during the vast majority of votes. Every Democrat in the Assembly or Senate voted the same way on about 86 percent of bills. Every Republican voted the same way on 76 percent of bills, according to the analysis of floor votes, which excluded abstentions and absences.

These charts show the percentage of members in each party voting the same way on every bill that came to a floor vote in the Assembly and Senate during the last two years.
