Sympathy pains from Boston, your East Coast counterpart. Since I live in Boston and have spent a fair amount of time in SF, I have tried to analyze which place is actually further left. I think SF has more blatantly crazy people with no grasp of reality, although when it comes to voting, it's about the same. Boston has a larger union thug component than SF, although these thugs will sometimes show a support for the military that is missing in your city. In both cities, the Dems will take 90 percent of the vote.
The conservatives in Boston have a better attitude though. In Boston, they have a wry humor about the mess that is local politics. In SF, they are just horrified and afraid.
