Edwards' Endorsement Of Clinton Imminent?

If John Edwards openly endorses Hillary Clinton, what could it mean to the nomination race? For starters, it would surprise a lot of Edwards supporters. Most of the unions backing Edwards have moved into the Obama camp, and they may be disappointed by Edwards going the other direction. However, one of Edwards' core constituencies of support was among white men -- who are now firmly in the Clinton camp (if exit polls are to be believed). So while either endorsement from Edwards is going to please some of his supporters and annoy some others, it's not outside the bounds of possibility that he would back Hillary, and influence voters as a result.

The problem for Edwards is that the window of opportunity to make such an endorsement (and have it be relevant) is fast closing. I have written about this before, calling on Edwards, Gore, and Richardson to make up their minds, already. And it bears mentioning that if Edwards endorses Clinton, but Gore (or, to a lesser extent, Richardson) endorses Obama, it could be seen as balancing out for the two campaigns.
