Which means Pelosi is free to do anything she wants, as her own party would never restrain her (especially at the time she promotes the agenda of the President from her own party) and Reps have no real political power to oust her. Be thankful to the people of California for this gift that keeps on giving.

The only way I could see a Republican winning SF is if he/she were a fiscal conservative/social libertarian.
Not that high; per current registration data [1], 37,719 registered Republicans of 437,529 total registered voters, so Republicans are 8.62%. Low teens is about what the typical Republican running in San Francisco gets on election day

If the political mood in San Francisco was running in a way that social libertarian positions were strong enough that they'd get enough liberal voters to hold their breath and vote for a fiscal conservative, then a left-libertarian would probably end up as the Democratic candidate in the general election, and win. (Although the main effect, given the way California's "open primary" works, would likely be a contested primary among Democrats resulting in the two candidates that make it to the general election both being Democrats.)
I suppose, though, if you the the surge of social libertarianism happens after the primary but before the general election, and the Democratic candidate isn't a social libertarian, you might end up with a chance for the Republican. But that's a pretty freakish scenario.
