LOL. You say that now. Just wait till that Gov race rolls around and no other than Boob Casey Jr is running against Corbett. If Smith knocks him out, it would be the next logical step or if Boob wants to move up to daddy's old job, he may do it even if reelected. He is the Rats best shot at that spot. The Casey's never have lost a General election in PA. Never.
Also I hear do nothing Corbett peed off the GOP rank and file as well forcing Welch as their guy. His credibility is shot and that isn't doing him any favors trying to run things around here. If he bothers to run things around here.
And if he loses this one to a random millionaire he'd go on to win the Governorship? I doubt that. And I doubt he'll run for Governor if he's reelected Senator as he probably will be. But even if he does and even if he wins it won't have anything to do with this Senate primary, this isn't Specter-Toomey, it was between several nobodies for the right to go on to probably lose to Casey, it is not gonna have long term political ramifications for Corbett, no matter how pissed off you may be about it today 2 and half years before the next gubernatorial election.
