"A decade ago politicians ran against LGBT rights; today, they're running towards them," he said.
What was left unsaid, of course, was that he and Clinton are among those who used to run against same-sex marriage but have since changed their tune.
And even as they've each positioned themselves as leaders and champions on the issue, they are hardly pioneers in their own parties. In fact, they jumped on-board well after gay marriage attained overwhelming majority support among Democrats.
Obama came out in support of same-sex marriage in 2012, and Clinton in 2013, half a decade after a majority of Democrats already supported it in public polling. But you wouldn't know about that from hearing them talk about just how much the issue means to them today.
In fairness, politicians are generally slower to "evolve" on issues like this than the general public. But given how much Clinton and Obama love to play up their support for gay marriage today (and even give us little history lessons), it's worth putting these things in context.
It's also further proof of just how quickly public opinion flipped on the issue, which in turn forced politicians who've been in politics for any significant amount of time to change their position. It could be some time before a pro-same-sex marriage presidential candidate doesn't have a flip-flop on the issue on their record.
On Thursday, Clinton tweeted a 1993 #tbt Throwback Thursday about healthcare after the Supreme Court ruled in favor of the Affordable Care Act.
Don't expect a similar '90s (or even '00s) throwback when the court rules on marriage, though. Her old position that marriage "has always been between a man and a woman" hasn't aged as well among her Democratic base.
