Indiana is not like Wisconsin which it does not border. It borders Illinois, Kentucky, and Michigan, all of which went for Trump.
It also borders Ohio which went for Kasich (only because he is governor), but even there Cruz was not 2nd place...Trump was.
I think Indiana is very much like Ohio as a rust belt agricultural state, but dissimilar in that the democrats haven’t made the inroads around the state that they have in Ohio.
Just remembered that one central issue that should really give Trump a huge advantage is his consistent message on how Carrier Air Conditioning left Indianapolis for Mexico. He mentions it in every speech/rally. Wish he could recruit some of the laid off employees for ads, etc. BTW, there were a couple who attended his rally last week, which he acknowledged.
