Gallup says Obama's support with white voters is similar to Kerry's. But is comparing Obama's support from a poll in early May, before a single shot has been fired in the general election, with Kerry's support from the exit polls of the 2004 race really apples to apples? It's perfectly possible Obama will meet or exceed Kerry's support among white voters in 2004. It's also possible he won't. Therein lies the point: six months before the election this seems like a nearly meaningless comparison.
