Which ones? I assume the Vincennes seat is one of them.
I had Battles in mind for a loss. I'm not sure how well you know your Representatives, but Vern Tincher, who's my representative, is retiring. Bob Heaton (barely lost to Tincher in 2008) is running again and should comfortably win. Nancy Michael is also in some serious trouble, as is Goodin and Blanton. And as far out as it sounds, I think Grubb could face a serious challenge as well from Sharon Negele.
Any other seats you had in mind? I mainly know about Southwest Indiana.
