Amid a series of protesters at the presidential hopeful's rally in Cadillac, Mich., one broke into a chant tauntingly linking the GOP presidential front-runner to the Ku Klux Klan.
“Get that guy out of here. Get him out of here!” Trump thundered.
“I think he should be arrested. Arrest him for what he just did and for the fresh mouth he’s got. I don’t want to give any recommendations, officer, but I would arrest him for a filthy, dirty mouth. And then we’ll see what his mommy and daddy say when they have to go and bail him out.”
The billionaire boasted that he’s completely stolen Cruz’s base of evangelical supporters, and claimed that social conservatives have fled the Texas senator because he’s proven to be a dishonest campaigner.
“Lying Ted Cruz, he gets up here and he holds up the Bible and then he puts the Bible down and then he lies," Trump said. "I’ve never seen a guy lie like this. He’s Lying Ted Cruz. He can lie about anything.
"The evangelicals, who I love, they got wise to lying Ted Cruz, and now every single poll, I’m winning the evangelicals," he continued. "I won in South Carolina. They don’t like liars. They don’t like liars. These are very smart people and they got wise to it."
Trump again mocked Rubio for wilting under fire from Chris Christie in a debate last month. And he conjured his exchange with Rubio from the night before over the size of his hands.
“Marco is sweating; it’s pouring down," Trump said. "And I thought he was going down, and because I wanted to show off what a good athlete I am, I wanted to show with the size of my hands how I could grab him. 
"I could grab that guy like nothing, boom, hold him up. I didn’t want him to get hurt hitting his head going down.”
The real estate mogul also kept the heat on Mitt Romney, who has begun a campaign to discredit Trump and stop him from getting the GOP nomination.
Trump called Romney a “choker” for losing the 2012 election, and said Republicans didn’t turn out for him because “he didn’t inspire people.”
Trump said the opposite is true of his campaign, complaining that he’s getting “zero credit” for electrifying the conservative base and bringing new voters — including Democrats and independents — into the GOP fold.
“One of the biggest stories is what’s going on for decades with this sleepy party where we were losing, losing, losing,” Trump said.
