-- David Gergen, 360 Contributor360 Program note: Anderson Cooper interviews John Edwards live at 10p ET
The assassination of Benazir Bhutto, potentially leading Pakistan to the brink of a civil war, would seemingly give a last-minute lift to candidates with experience in national security, especially Hillary Clinton and John McCain and, yes, Joe Biden. But Iowa may have its own dynamic heading toward the caucuses -- a good reason to keep your eye on John Edwards as he appears on AC 360 tonight.
Iowa polls show that Edwards, once the darling and then the candidate who faded, has been rising recently, now virtually deadlocked with Hillary and Barack Obama. More importantly, Edwards has practically lived in Iowa so that he has built up a veteran organization, may be ahead in rural areas, and is a strong second choice among potential caucus goers.
For Hillary Clinton, the nightmare of Iowa would be an Edwards surprise accompanied by a strong showing by Obama. She can probably afford to come in second in Iowa but to finish third would be highly dangerous. Howard Dean came in third last time out and he was on his way to the showers. So, even as we watch the Clinton-Obama duel, keep a close eye on Edwards.
