WEST LAFAYETTE, Ind. (AP): Some Indiana supporters of Vermont senator Bernie Sanders aren’t certain they would support Hillary Clinton if she defeats him for the Democratic presidential nomination.

About 1,000 people attended a Sanders campaign rally Wednesday at Purdue University in West Lafayette ahead of the state’s primary election next Tuesday.

Thirty-year-old Megan Wills of Frankfort says she wouldn’t vote for Clinton. She says the Democratic front-runner flip-flops too much on issues, while she believes Sanders says what he means.

Eighteen-year-old first-time voter Salvador Rodriguez of South Bend says he’ll support any Democratic nominee in the November election.

Sanders also was holding a rally Wednesday night at Indiana University in Bloomington. Clinton made campaign stops Tuesday in Hammond and Mishawaka.
