Possibly, but I believe there exists a "pendulum effect," otherwise you would never have seen a Republican comeback after a Democratic takeover in government. But think about the Prop 8 numbers being so marginal. At the time of the election, the Gaystapo had possession of the ball - they had managed to have homo-"marriage" in place, creating the effect of "taking away rights" if the proposition won; they had numerous celebrities crowing about this issue in their favor; had the CA attorney general, who was SUPPOSED to be defending Prop 8 but was in their corner; had the wording of the proposition changed to a derogative connotation; and had 18,000 "marriages" already in place, giving them a wedge to push the issue. By all accounts, this thing should have been a blowout for the homo-nazis, so I think the win for us was impressive.
IMO, their proposed ballot amendment to dump Prop 8 will probably result in a reversion to the 61% support for traditional marriage, if not higher.
And the libs were crawling out of the woodwork to elect the first marxist President. I think anti-prop 8 will go down in flames.
