Actually, the establishment and talk radio are not so universally anti-Trump like it was in Wisconsin. Pence hasn't endorsed and it seems that he won't, considering that he's up for re-election this year and it could unnecessarily stoke opposition to his bid if he endorsed either candidate. Indiana will likely be much more pro-Trump than Wisconsin - for a wide variety of reasons.
Indiana is more Illinois than Wisconsin. All of the surrounding states, but for Kay-sick’s home state of Ohio has gone into the Trump camp.
It’s not an Upper Midwest or Mountain West/Plains state where Cruz has traditionally done well this cycle.
