INDIANAPOLIS (AP): The Indiana Secretary of State’s office says voters should plan ahead as the state’s May 3 primary election approaches.

Voting centers are scheduled to be open from 6 a.m. to 6 p.m. on Election Day, though voters can still visit their local county clerk’s office to cast their ballots before then.

Early voters have so far surpassed previous turnout rates and some election officials expect that trend to continue until May 3.

Presidential candidates are planning visits throughout Indiana in the coming days in an effort to find support during the last week of campaigning.

For example, GOP candidate Donald Trump plans to appear with former Indiana University basketball coach Bob Knight on Wednesday. Democrat Hillary Clinton plans rallies in Hammond and Mishawaka on Tuesday.
