There are lots of ways to gauge how conservative or liberal your city or town is: voter registration and election results being two of them.

But a new analysis by the Silicon Valley start-up Crowdpac looks at campaign contributions. The firm believes it's the best way to identify where a politician stands is to look at where they get their money.
