Thus spake Obama, supposedly in favor of gay marriage.
Just read that. Personally is the operative word. As in "I personally have no issues if gay people want to marry, but for crying out loud, do not expect me to spend any political capital on it"
So for the four years that Obama has evolved, he has gone from not supporting gay marriage to mouthing his support for it. But that's about it.
This should be disappointing to even the most ardent of his supporters, but the Overton window has shifted so far to the right, that it seems like a major shift on his part.
So what's he going to do?
Well, nothing. He is going to leave it to the states after stressing that it was only his personal opinion.
Had slavery been left to the states, would he be President today?
