In a move that has surprised many pundits, John Edwards has dropped out of the democratic race. In New Orleans he said that Obama and Clinton had both pledged to make ending poverty a key cause of their campaigns:
"they will make ending poverty central to their campaign for the presidency."
"This is the cause of my life and I now have their commitment to engage in this cause,"
It's not clear how much Edwards support will flow to Clinton and Obama though the next set of tracking polls should be very interesting. I'd wildly guess it'll split about equally between Clinton and Obama.
Dick Morris was suggesting that the Florida results indicated Obama is moving up fast on Clinton, citing the fact that those who made a last minute decision were split between the two where earlier deciders went for Clinton. I'm not clear he's got the math right on this however, since this tell us something about "last minute deciders" rather than about the broader electorate. He felt this was like a tracking poll trending strongly in Obama's favor, but I think that is not mathematically sound reasoning.
