Then you have given up. But you really are just wrong. I suspect Indiana has a more open primary than most states, fewer signatures and the like needed to get on the ballot than many other states. There actually are three elections, getting on the primary ballot, the primary, the election.
Complainers usually start a few weeks before the election but do nothing when they could have as evidenced by defeatist claims that play right into the hand of the COC. Conservatives usually put too many options on the primary ballot then the COC candidate wins…
