More than in any other state.
If that were the case, you would have been a "red" state instead of Kerry "blue"! Now if you stated there were more liberals than any other state, it could not be disputed.
I have no doubts there are a great number of conservatives in California, but hardly enough to make a dent in the liberal left wing populace in the same geographic space. When was the last time CA went Pubbie in a presidential election? Reagan?
I believe Texas has the greatest conservative populace concentrated in a single state.
Now if you want to bring percentages into account, I'll put my state of Idaho right up there in the top 3.
