INDIANAPOLIS (AP) — Donald Trump is ramping up his presidential campaign in Indiana, but it’s already running behind.

The Trump Indiana campaign is opening offices Wednesday in Carmel and Evansville and Thursday in Fort Wayne.

Indiana’s primary election isn’t until May 3, but 27 of the state’s 57 delegates have already been selected at congressional district caucuses. The deadline to register as a candidate to become a delegate was March 15.

If Trump doesn’t win on the first ballot at the national convention this summer in Cleveland, most delegates no longer are bound to support the winner of state party primaries or caucuses and can support the candidate of their choosing.

Tony Samuel, vice chairman of the Trump Indiana campaign, says it’s “definitely” concerned about the delegate rules.
