Some anti-Trump people are pro-Cruz (the Mike Pence people in Indiana). Some anti-Trump people in IN are pro-establishment (the Dick Lugar people). Some anti-Trump people in IN don’t know who they are for... just who they are against.
Not all anti-Trump people are the same.
Not all pro-Trump people are the same, of course.
I thought you were going to say some are just Hoosiers who are clueless about all of this!
