I'm concerned about his weakness in Indiana. He prevailed by 2.95% in Indiana in 2012, even as Mitt Romney won Indiana 54.04-43.84%. Why the weakness?
That said, he could be a compelling candidate. 55 is a decent age, he's from a conservative state, and has a record of conservatism.
He was running for an open seat against what seemed to be a fairly strong Democratic candidate. And the good Libertarian showing suggests Mourdock's awful Senate candidacy may have poisoned the well for the other non-presidential statewide races.
