I'm more than a little surprised that nobody in this thread has stood up to explain how DC is the most liberal city.
This is a place where Obama got
86 percent of the white vote, which is more than he got from the entire population in San Fran.
I think you probably could make a case for the Bay Area being the most liberal metro area, however.
...
Also, if you just look at the area within the city limits, I think Philly is more liberal than NYC. While there are definitely some conservatives in South Philly and the far Northeast, you don't have anything like the monolithically R South Shore or Borough Park here.
