For those not concerned about character, the Castle/O’Donnell issue in the Delaware Senate race comes down to a straightforward calculus of electability versus ideology.  The implicit argument from some has been that they cancel each other out in this case.  Castle is a useless RINO and O’Donnell is an unelectable conservative.

But I would disagree that Castle is a useless RINO, or really that he is a RINO, a “Republican in Name Only,” at all.  He’s a moderate, northeastern Republican.  There’s a difference.
