In new ad, Obama to Romney: Be more like John McCain!

In all likelihood, running around with America's favorite game show host Donald Trump is not going to help Mitt Romney win any votes. Especially not with Trump still talking about President Barack Obama's birth certificate.

At the same time, being more like Sen. John McCain (R-Ariz.), who lost the last presidential election to Obama, would also not help Romney win any votes. But in a new ad, that's the route Obama's campaign suggest Romney take.

Why wouldn't Obama want Romney to be more like the guy who lost last time?

"As the Republican nominee, John McCain stood up to the voices of extremism in his party," the ad says. "Why won't Romney do the same?" The ad then shows various clips of Trump from last year obnoxiously suggesting Obama might not be a natural-born citizen.
