Not all-- same-sex marriage was approved by voters in Maine, Maryland, Minnesota and Washington State, and by elected legislatures in Washington, D.C., Connecticut, Delaware, Hawaii, Illinois, New Hampshire, New York, Rhode island and Vermont.
Was this before or after the massive media propaganda onslaught normalizing homosexuality?
I see that in the case of Maine, the legislature passed a "gay marriage" statute, the statute was overturned by a vote of the people, and the Gaystapo forces then pushed for a new referendum, which then passed, or so they tell us anyway.
So what changed? Well the Bastard in Chief had a conversion. You see, before he was against it, but in 2012 he became in favor of it. Liberal Maine could not stomach the idea that they might have a position different from their Holy Affirmative Action Boy-Friend, and so the rank and file "Good Democrats" sallied forth and changed their minds to get back in compliance with his new epiphany.
The Black vote makes up 13% of the electorate, and that is more than enough to swing the issue in the opposite direction. They simply march in lock step with whatever that bastard says. So do many white Liberals.
I guarantee that if Obama came out against it again, they would dutifully repeal it.
