You have to hand it to the far right. If nothing else, they're phenomenally subtle.
Case in point: as the Republican loss of power in the House appears inevitable, the NRCC, the RNC, and assorted other right-wing blowhards have started trying to turn the election into a referendum on Nancy Pelosi as Speaker of the House. Part and parcel of this strategy is frequently using the "San Francisco liberal" epithet at every possible opportunity.
Now, Nancy Pelosi is an idiot. Approximately 90 seconds of conversation is more than enough to exhaust her knowledge of any single issue. But in this case I'm more bemused by the Republicans' "clever" rhetorical strategy than I am turned off by Pelosi.
"San Francisco liberal?" Get it? GET IT? (*nudge* *wink*). We know you rural folk don't like them "San Francisco" types! Isn't it awesome how well that term allows you to feign ignorance when people call you a homophobe?
Why, whoever said anything about gays? We were just talking about those "San Francisco" liberals! Hee hee!
Cute. So cute.
