It is possible she may try to go for it, but the Clintons are yesterday's news and she will be even more stale by 2008.
The Dems desperately need fresh faces and Edwards is one of them -- and proved it in the primaries. I don't like his politics, but he will be a vote getter.
If Edwards has any White House aspirations, he's sure going about it in an odd way. He won't be running for re-election in the U.S. Senate, so he's going to be out of the limelight completely for at least another four years.
