I'm keeping track of the 2014 vote in two spreadsheets. Here is the 2014 v. 2012 California Assembly vote. While there are 80 assembly districts, only 48 are included here. That's because the other 32 didn't have one Republican and one Democrat running in either 2012 or 2014. So there's nothing to compare year to year.
Here is the 2014 House of Representatives vote. I'm attempting to keep the numbers as up to date as possible. I don't include write-in votes if the name of the candidate isn't included on the Secretary of State website. For all we know, that write-in could be Mickey Mouse. If we include unknown write-ins, we might as well include blank ballots as votes.
California Congressional 2014 v. 2012 is here.
