Live on YouTube, sundry pundits discuss the fact that Barack Obama would be a stronger general election candidate matched up against John McCain. As readers know, that’s certainly my view. And it’s certainly the view of Democrats running in “red” states who feel he’d be better for down-ballot candidates than would Hillary Clinton.

It’s been my experience, though, that it’s basically impossible to convince people on this score. At the end of the day, there’s a ton of uncertainty surrounding this question and there’s nothing one could do to prove things one way or another. Given the uncertainty, it’s open to people who like Clinton to just insist that, well, sure, Obama’s more popular now but things would look different after a campaign.
