"San Francisco values" is one of those great political phrases that apparently never needs to be defined to be employed effectively. Presumably, it scares the bejeezus out of midwestern white voters, so Republicans use it promiscuously in attack ads.
Here's just such an ad, put together for U.S. Rep. Sam Graves (R-MO) as an attack on challenger Kay Barnes, the Democratic mayor of Kansas City. This, I'm pretty sure, is what Missouri Republicans think San Francisco looks like:
It would have been a lot of fun to be an actor in this ad. The image of the black guy in the cowboy hat "dancing" with two women to a low-grade disco beat has to be one of the least San Francisco things I've ever seen. It looks more like the Thompson Twins teaching lambada at a retirement home in the late 80s.
