That particular was just not a major player in this election. Again, I live here--and I never, ever heard anyone bring that up (except me, of course). That issue was trumped BIG TIME by the Toll Road, Iraq War, Mitch Daniels, and loss of manufacturing jobs in the region (not necessarily in that order).
When Donnely votes along party lines on Gun bills, abortion, taxes, border security and the like, I think the next Republican candidate will take the side of the Toll Road, hopefully the Demorats can fix Iraq and that wont be an issue/sac, be against Mitch and then tell the folks that he/she will vote to repeal all the gun laws the dems made, and he promises never to side with a liberal, then he/she could win easily.
