Will Obama's DNC nomination convention be struck by hurricane Bill Clinton?

Will hurricane Bill Clinton blow into Charlotte and rain on Obama's coronation as party nominee for 2012?

Clinton’s got a prime-time speaking slot on Wednesday night, but Charlotte will be full of chances for him to freelance on camera or speak just a bit too candidly about Obama. Republicans will be ready to pounce on Clinton if he credits himself instead of Obama for positives, or expresses doubts about an Obama proposal. And then there’s the possibility Clinton could suggest support for a Republican plan, like he seemed to in June regarding the competing proposals over extending the Bush tax cuts.

Interestingly, Bill Clinton won't let Obama know  in advance what the content of his speech is.

The Obama campaign has insisted on seeing the speech before Clinton delivers it, and Clinton has just as insistently refused to show it to them. As a result, no one — not even the president — knows what Clinton intends to say. This has led some Democratic insiders to speculate that Clinton will make not-so-flattering remarks about the last four years of Democratic rule in the White House. 

“If I were the president,” one of these insiders told me, “I’d wake up at night in a cold sweat wondering what surprises Clinton is going to come up with.”
