It seems the story is starting to seep out. Edwards better get out on top of this or his political career is dead.
Of course, Edwards has been a private citizen for 4 years now, mostly spending his time making a lot of money at private equity house Fortress and running another ill-fated Presidential campaign, so he has no seat to resign. I don't really think that he was a serious contender for the VP slot with Obama. He doesn't deliver any swing states. He couldn't even deliver his own state for Kerry in 2004. (Which reminds me of why Pawlenty is such a pointless choice for McCain - Minnesota hasn't gone to the Republicans in any of the last seven elections. I doubt it will go Republican in the middle of Obamania.) Most important of all, choosing the other Democratic candidate beside Hillary would not do much to fix Obama's problem with pissed off Hillary supporters.
So, Edwards does seem kind of politically pointless at this time and that does give the MSM some latitude to claim that there is no public interest in his private life. Then again, we are talking about a guy who ran a competitive campaign for President and made a big deal of trotting out his wife and her medical condition for his political gain.
