Do I vote in the Indiana Republican or Democratic Primary?

it all depends on what your registered as.....if your a registered republican, your going to have a ballot for the republican primary which right now is uncontested. if you're registered as a democrat your going to choose which democrat you want to run for president in november. if you are registered republican, but want to make a difference, you're going to have to change party affiliation at the polling place...one thing for sure though, in november it doesn't matter what party you are registered for, you will be able to vote for anyone in november for the presidential election. all in all, it is up to you.
