Come on in, the water's fine at the Candidate Death Pool

The candidate death pool has far fewer participants than I thought it would have by this point. Right now the only Democrat in it is Gov. Vilsack while Tom Tancredo has his white swim vest on, Duncan Hunter has long been relaxing with a mojito in the deep end, and Sam Brownback has modeled his modest swimwear for a while now. Who will be doing a drunken cannonball into the shallow end of the campaign death pool by Friday night? Fred Thompson is rumored to be willing to drop out if he places 4th or worse in Iowa... who else? Or will the one week sprint to New Hampshire provide enough (false) hope for everyone to stay in for one last college try?
