Delaware Attorney General and Joe Biden's son Beau will not run for his dad's old Senate seat despite being damn hot.  Do you think he's ever done a Cosmo layout?  Anyway, this leaves the race without a single strong Democratic candidate to run against Republican Rep. Mike Castle.  Will Joe Biden's seat follow Ted Kennedy's and become a GOP pick-up?  If only someone in Delaware could provide some insight...
