The Hill had an article out yesterday naming the top 13 targets for the NRCC. In other words, the 13 races House Republicans feel are most vulnerable to switching, one way or another.
Two of those targets are Ohioans Steve Chabot and Steve Stivers.
As I've stated before, when you combine recent generic congressional ballots from pollsters like Rasmussen along with the changed likely voter demographics, the 1st and 15th districts won't be any more vulnerable than they will be in 2010.
A side benefit of the money and energy that will go into these races goes to John Kasich. While the 1st CD went to Blackwell in 2006, the 15th went to Strickland. Taking advantage of the GOTV efforts behind each of these congressional campaigns will only help Kasich as he works to get conservatives to the polls.
