Corbett is not popular. He inextricably linked to the Sandusky scandal at Penn State and that has hurt him across political spectrum.
The Pennsylvania Governorship has swung like a pendulum (8 years in GOP hands, 8 years in Dem hands) for the last 40 years.
The Penn State problem , his perceived favoritism of out-of-state interest in regards to the fracking boom, and his circumventing his own party system to hand pick his preferred candidates for last year's state-wide row office elections (some of the candidates he insisted on lost badly) have combined to create a situation where Corbett honestly appears to be a risk of being a 1-term governor.
He may even face a credible primary threat.
Earlier this week, he announce the state would be suing the NCAA in relation to penalties against the Penn State football program. Its a pretty transparent p.r. move to endear himself to Penn State supports (Republicans and Central PA Dems). Inital reviews of his idea seem decidedly mixed.
Today (for the first time since his election) he is appearing on local Harrisburg Public interest radio show "SMART TALK" on local NPR station WITF FM 89.5. It seems a very deliberate next step in his p.r. rehab.
I'm not really interested in what he has to say (he's a never ending stream of B grade bullshit). I am interested in hearing the tone of the public calling in to ask Corbett questions.
I am very hopeful he will receive a strong primary challenge. Usually, for PA Governorships, the party out of power just phones it in for races against an incumbent governor (for example, a few years ago the GOP offered a literal Hail Mary pass against incumbent Ed Rendell by nominating former Pittsburgh Steeler wide receiver Lynn Swann. I think the Dems ought to be going with their "A game" candidate for 2014. You have a rare chance here.
