DJ, that “rumor” doesn’t pass the laugh test. If Castle was in cahoots with Obama and Biden to give the Senate seat to Beau Biden, Castle *wouldn’t have run for the Senate in the first place*. If Castle truly was a Democrat mole within the Delaware GOP (as opposed to a socially liberal-to-moderate Republican), Castle would have asked Obama to name him to some plum position in 2009 and the RATs would have won both the House and Senate seats without any drama. Why the heck would Obama and Biden prefer to have Castle run for and win the Senate seat?
Sometimes a cigar is just a cigar.
The more I’ve seen over the years about the collusion between Democrats and the Republican Establishment, the more such rumors are anything but far-fetched. I absolutely believe this is what he would’ve done.
