Via Philip Klein, who says after watching this that if Hillary has merely “evolved” on gay marriage then Peter Parker merely “changed slightly” after being bit by that spider. I don’t begrudge anyone a sincere reversal on SSM; I had one myself, like millions of people over the past 10 years. But she’s laying it on awfully thick here. It’s one thing to weigh the pros and cons of gay marriage and change your mind, it’s another thing to decide, hey, maybe this “sacred bond” on which all of civilization is based isn’t so important after all.

Quick — Hillary Clinton or Rick Santorum?

…the fundamental bedrock principle that exists between a man and a woman, going back into the mists of history as one of the founding, foundational institutions of history and humanity and civilization, and that its primary, principal role during those millennia has been the raising and socializing of children for the society into which they are to become adults.

It’s not every day you find a pol reversing themselves on a policy they’ve previously defended by citing the “mists of history.” But whatever. We know from Obama’s 2008 lies about gay marriage that the left won’t punish her for this. They don’t need to. Support for SSM is now so firmly a litmus test for Democratic leaders that she wouldn’t dare cross them once in office, whatever her true feelings might be. There may be value in this clip, though, if it shames Hillary into staying away from the issue during the general election campaign. I think she’s likely to do that anyway: The fact that she supported gay marriage so belatedly relative to other top Democrats, even endorsing a state-by-state approach instead of a Supreme Court ruling as recently as last year, means she can’t be too aggressive in slamming the GOP nominee as anti-gay. Or … maybe she can. Maybe I’m giving America too much credit in thinking it would demand a shred of logical consistency on this subject. It’s a sad hallmark of the SSM debate, after all, that recent converts to the cause feel no qualms about slamming the other side as hateful bigots for holding the same position those converts held themselves 15 minutes ago. Maybe Hillary Clinton, defender of “foundational institutions of history and humanity and civilization,” is exactly the right person to be a shrill fingerpointing demagogue about gay-marriage heresies in 2015. Sounds like Marco Rubio’s getting prepared, just in case.

Exit question: Any other “sacred” bedrock principles of human civilization, by her own accounting, that Hillary feels like revisiting? We should probably know upfront.
