That was after the primaries. The point was Bernie's messaging did not resonate as well in the south compared to Hillary based on the voters.
That's something he'd still need to overcome or at the very least address going forward. And I think its largely because of how he speaks on social issues.
But he's certainly popular. I'm not here to argue that. I did see a poll that had him less popular than Joe Biden vs Trump just a few days ago. I didn't really dig into it though. And no, I don't want Biden running for President either.
