Barack Obama has been surging in the polls, and now the Obama campaign is bringing out the big guns.

Bill Clinton campaigned today for Obama in Florida. John McCain’s lead has evaporated in Florida and Ohio, and some polls show Obama with a lead in those states. Clinton can be a huge help getting independents and Democrats to fall in line for Obama, particularly in the current economic environment.

Up to now Clinton has been a liability. He’s terrible in interviews as he can’t hide his disapointment that Obama beat Hillary for the nomination. But on the stump he’s a huge asset. He knows how to give a speech, and he knows how to frame an argument that will persuade voters. If he keeps this up and Hillary continues to hit the campaign trail, Obama should be able to close the deal.
