New York = Jew
San Francisco = Homosexual
Elia thinks both are ridiculous. I'll agree with the former, but he's delusional if he thinks the latter isn't in play. Totally coincidentally, Elia doesn't even try to say what conservatives mean when they talk about "San Francisco liberals" (nor do the other blogs who commented), preferring to focus on Pelosi herself:
Nancy Pelosi = "Over-her-head, out-of-touch-millionaire, with rhetorical skills that make George Bush look like Cicero."
Well, perhaps, but that certainly isn't what springs to mind when one thinks of San Francisco. It does absolutely nothing to explain why Republicans love to harp on the fact that Pelosi is from the city of the Golden Gate. Is there something about San Francisco that makes it entirely a bunch of "out-of-touch-millionares"? Or is it famous for its poor rhetorical skills? Please. What the heartland thinks of, when it hears "San Francisco" in a political context, is its large gay community. San Francisco = pro-gay. There is no way Elia can be a serious observer of politics and not know this.
In other words, sure, there are plenty of angles of attack on Nancy Pelosi that have nothing to do with homosexuals. But they also have nothing to do with San Francisco. Once you start mentioning "San Francisco" in the ads, you have to give me a convincing reason why you'd bother bringing it up. The self-evident answer is the gay symbolism.
(Incidentally, the reason this doesn't apply to "New York Times" is that NYT is a stand-alone proper noun. If Republicans started talking about "New York liberals," then they'd have to explain the symbolism behind that, but talking about the NYT and talking about New York are not the same thing).
