I didn't see any rabid, lefty protesters, but the fact that the ridiculously large police presence (guess they were afraid the mobs with pitchforks might come for the Christians!) had closed off nearby streets to traffic might have had something to do with that.
Anyway, it was a glorious sight to see in SF, that's for sure.
The lefty protestors were along the Embarcadero. They weren't in great numbers this year and one of the newschannels reported that Planned Parenthood didn't organize the counter-rally this year, but they still got face time on the channel I watched.
