If a former Governor whom has never lost an election (Gilmore) is a “weak” candidate, I wonder what you consider a “strong” candidate to be ? Tom Davis would’ve lost by an even wider margin, and we have no idea how General Pace would perform.
He may be "right" on the issues today, but most Virginians are not going to be so forgiving, based upon his prior performance as governor. That's what makes him weak.
