Kerry's Vote on Iraq

President Bush charged Democrat John Kerry with shifting positions on the Iraq war as he opened a five-day campaign swing in Florida.

The Bush campaign has been pressuring Kerry to say whether he would have still voted for the Iraq war given the fact that no weapons of mass destruction have been found. Kerry on Monday said he would have voted to give the president authorization to use force against Iraq "but I would have used that authority effectively."

Bush says it's further evidence of Kerry flip-flopping on the war effort. The Kerry campaign says polling data show Florida veterans are starting to move toward the Democrat's side due to the turmoil in Iraq.

Tonight we take a look at why Kerry says he's sticking by his decision to support the war in Iraq.
