Businessman Mike Braun released a new television ad Monday in which he strolls around town mocking his rivals – Reps. Luke Messer and Todd Rokita – in the Indiana GOP Senate primary as a couple of cardboard cutouts. Mr. Braun, a former state lawmaker, has emerged as the wildcard in the May 8 primary election and has campaigned as the outsider, saying it is hard to tell the difference among career politicians like Mr. Messer and Mr. Rokita.
