Donald Trump made his pitch to evangelicals in Iowa Saturday, comparing the treatment of Christians to Muslims at a rally in Sioux Center.
"Christianity is under tremendous siege," Trump said, later calling Christians "the strongest lobby ever."
The Republican front-runner recalled the public backlash to his suggestion late last year that the U.S. ban Muslims from entering the country on a temporary basis.
"If I said that about Christians, I would have less backup than by saying it about Muslims," he said.
"I get elected president, we're going to be saying 'merry Christmas' again," he added.
With the Iowa caucuses less than two weeks away, Trump has ratcheted up his attacks on Sen. Ted Cruz, who has threatened his lead in the Hawkeye State.
"Ted has a lot of problems," Trump said. "Number one: Canada."
The real estate mogul continued to cast doubt on Cruz's eligibility for the presidency given the fact that he was born in Canada, although he is a naturalized U.S. citizen.
"Everybody assumed that Sarah Palin was going to go with Cruz," Trump said, touting the former Alaska governor's endorsement of his campaign earlier this week.
"He's very devastated that he didn't get Sarah Palin," Trump added.
Trump currently sits at second place on the Washington Examiner's presidential power rankings.
