WASHINGTON (AP): Donald Trump has won the Republican presidential primary in Indiana, continuing his surge toward clinching the GOP nomination.

The win for Trump is a blow to Ted Cruz, who will fall further behind the billionaire in the race for the 1,237 delegates needed to claim the Republican nomination.

Among his supporters Tuesday was Roger Willett, a 51-year-old Republican who says he has been a Trump supporter since the businessman’s campaign began.

Willett works as a driver escorting oversize truck loads and complained that the economy in rural western Indiana offers few prospects, particularly for people just getting out of school. He says he’s tired of voting for career politicians and called Trump “a working man, for us.”
