Say this for Bill Clinton: he does good make-goods. Last week,  the Obama campaign was miffed — some staffers were livid — over the former president’s off-message remark that Mitt Romney's record at Bain Capital was “sterling.” This was a particularly unhelpful remark in the wake of Newark Mayor Cory Booker’s similar comments.

But last night, at a fundraiser, Clinton, undoubtedly with a nudge from the Obama staff — some of whom have worked for both men — got back on message. Romney’s economic ideas would be “calamitous” for the country should he be elected, the former president told the gathering.

One might be tempted to write off this remark as a little too obvious, but I spoke to several people who attended the event and whose judgment I trust. Their view: Clinton was a powerful advocate for President Obama last night. He made a great case for the president’s economic policies and contrasted them effectively with Romney’s. Just a reminder that when Clinton is good, he is really good.
