After laughing at the clip from the SNL sketch in which Clinton tries to appeal to young voters who have gravitated toward his campaign, Sanders said there's a sense of "satisfaction" that Clinton's stances are starting to mirror the Vermont senator as he continues to run to the left of her.

“I think Secretary Clinton is catching on to where the American people are,” Sanders said at an MSNBC town hall moderated by Chuck Todd.

“And, you know, she has evolved on the Keystone Pipeline. She has evolved on the Trans-Pacific Partnership. She has apologized for supporting the war in Iraq. She's apologized for supporting this homophobic [Defense of Marriage Act] legislation of the 1990s,” Sanders continued.

Sanders has pointed to many of these issues to draw contrasts between himself and the former secretary of State. He frequently uses her 2002 Iraq War vote as a wedge issue when discussing foreign policy differences.

But the Vermont senator went on to question whether she'll have to evolve on where she stands now later down the road.

“So yes, I suppose one can get satisfaction from seeing her move closer to our positions. But I think what the voters have got to decide is — will she be apologizing 20 years from now for actions she takes today?” Sanders said.

“What leadership is about is having the courage to do the right thing now even if it's unpopular. And I think if you check my history, that's what I've done,” he added.
