The man suddenly favored to win Joe Biden's U.S. Senate seat wasn't even supposed to be in the race, if most pundits are to be believed. State Democrats were lining up behind the vice president's son, Delaware Attorney General Beau Biden.
But Biden unexpectedly decided not to run. And other Democrats took a pass on what was thought to be, at best, an uphill general election climb against veteran GOP Rep. Mike Castle.
Now, with Castle defeated in the primary, Coons suddenly finds himself the favorite against arch-conservative upstart Christine O'Donnell.
