Umm... they named half the rust belt states, and then claimed the rust-belt wasn't a key region to focus on? West Virginia was already going to the Republican nominee, and Illinois and New York were already going to the Democratic nominee. So basically what they've said is "all even remotely competitive rust belt states but one (Indiana) are getting Clinton's attention," which makes the latter statement about not putting money in the rust-belt pretty perplexing.
EDIT: I think I misunderstood. I think the mention of Wisconsin, Michigan, and Pennsylvania was to be interpreted as states where Clinton isn't putting a lot of money yet, meaning only one rust belt state (Ohio) has her undivided attention as of yet.
