As I've been saying since February, I think that the great question of the 2008 campaign will be whether Barack Obama can unite Democrats to a great enough degree to win. (Corollary to that is the question of whether John McCain can unite Republicans enough to take advantage of any Clinton-Obama fallout, and to overcome the massive partisan advantages of Democrats this year.)
Real Clear Politics takes a stab at answering the question of how many Clinton supporters will support McCain, using current (very early!) polling:
Luckily, we have some data from Quinnipiac's recent swing state survey that gives us some indication of how Clinton primary voters in Florida, Ohio, and Pennsylvania are feeling. As you can see, Florida closely mirrors the national numbers but the trend is more pronounced in Pennsylvania and especially Ohio, where the net change (drop in support for Obama/increase in support for McCain) reaches 22 and 29 points respectively:

Again, it should be noted that Obama increased his lead over McCain in every Quinnipiac state poll, indicating that despite whatever lingering fallout exists with Clinton supporters, Obama is more than making up the difference with gains among other groups.
Still, it should give the Obama campaign a bit of a pause to see that, at least for the moment, one in four Democrats who voted for Hillary Clinton in the primaries in both Ohio and Pennsylvania indicate they will crossover to vote for McCain in the fall.
I really need to sit down and do my own analysis on this. I keep waffling on whether Obama is doing a great job winning Clinton supporters and I just haven't had a chance to compile and drill down into any real data yet. But I wanted to share this anyway.
