(LA PORTE, Ind.) — Back in the part of the country where he last lost to Ted Cruz, Republican presidential front-runner Donald Trump is confidently pushing for a win Tuesday in Indiana that he argues ought to knock the Texas senator out of the race. Buoyed by a sweep of last week’s primary elections along the East Coast, the billionaire businessman appears to have learned a few lessons from his defeat last month to the Texas senator in nearby Wisconsin. There have been no slip-ups on talk radio in recent days, nor stumbles over issues that matter deeply to Republican voters.
