If Mike Castle ran, he's in a position to do some serious damage... but we have no indication that the 71-year-old congressman is seriously mulling this race, other than being on the receiving end of a series of pleas from John Cornyn. While a campaign against Biden would force a grueling schedule on a guy who's run into some health issues in recent years, and would undoubtedly attract a great deal of national money, he starts off the race with solid approvals: 54-33.
PPP will release re-elect numbers for Castle against former Lt. Governor John Carney on Thursday. That should be interesting to see, but I suspect Castle will again start off in strong shape.
