It's a measure of the failure of Mike Pence as Governor of Indiana that he is suddenly vulnerable to defeat in the 2016 elections.
People from outside the state have this idea of Indiana as an unrepentantly Republican. Yet in the last 25 years, Democrats controlled the House for 17 years, and the Governor's office for 14 years. With the exception of the Senate, Indiana has been a competitive state for Democrats at the state and local level. Which is why the "unexpected" vulnerability of Governor Mike Pence feels all but that to people who've followed Indiana politics for long enough.
Which is why news the former Indiana House Speaker John Gregg is running has been greeted with considerably more enthusiasm nationally than in the Hoosier state. Mike Pence's relationship with the Koch Brothers political network is well know. His willingness to front for awful ALEC model legislation has been making progressive Hoosier facepalm since long before this RFRA mess caught the rest of the country's attention.
The problem is that Pence's prospective opponent John Gregg has a Koch problem, or more to the point ALEC problem too.
If John Gregg wants to prove that he's not PWNED by the Koch Brothers/ALEC, he's got to own up to the fact that he has this ALEC connection. He hasn't. Forgive me if my enthusiasm for replacing Pence with another Koch pawn is lacking.
