Sen. Ted Cruz and Gov. John Kasich ganged up on front-runner Donald Trump on Tuesday over battery charges filed against his campaign manager, while all three contenders expressed misgivings about their pledge to support the party’s nominee.

The candidates appeared separately at a CNN-televised town hall meeting in Milwaukee amid fresh signs that the party is badly divided a week before Republican voters in Wisconsin cast ballots in the primary.

Perhaps no question caused as much rhetorical gymnastics as a query about The Pledge. At the first Republican presidential debate back in August, all of the candidates — except Trump — raised their hands when asked if they would support the eventual nominee of the party. Although he declined then, Trump also later signed the pledge.

“No, I won’t,” Trump said when asked if he would keep his pledge to back the eventual Republican nominee were it not him.

“No, I won’t,” Trump said when asked if he would keep his pledge to back the eventual Republican nominee were it not him. Trump told moderator Anderson Cooper that he has been treated unfairly. By whom? “I think by, basically, the RNC, the Republican Party, the Establishment,” he said.

The candidates did not sound nearly so committed on Tuesday. Cruz did not directly answer the question but said he is not in the habit of backing people who insult the wives of other candidates.

“Let me tell you my solution to that: Donald is not going to be the GOP nominee,” said Cruz. “We’re going to beat him … Nominating Donald Trump would be an absolute train wreck. I think it would hand the general election to Hillary Clinton.”

Kasich suggested he had been too rash to commit to supporting the nominee regardless of the circumstances.

“When you’re in the arena, you develop respect for the people in the arena,” he said. “But I’ve been disturbed by some of the things I’ve seen, and I have to think about what my word and endorsement would mean in a presidential campaign. So I want to see how this thing finishes out.”

Kasich declined to say whether Trump had met that standard. But he quipped, “I sure hope they’ll endorse me for president when I’m the nominee coming out of the convention in Cleveland.”

For his part, Trump said he doesn’t need Cruz’s support. “Honestly, he doesn’t have to support me,” he said. “I’m not asking for his support. I want the people’s support … I don’t really want him to do something he’s not comfortable with.”

Cruz and Kasich both said they would have fired Trump campaign manager Corey Lewandowski following Tuesday’s criminal charges in Jupiter, Florida. Police charged him with a misdemeanor offense, accusing him of manhandling a former Breitbart News reporter at a news conference earlier this month.

“Of course I would,” Kasich said. “When you have problems like that, you have to act.”

Cruz said the same thing.

“It shouldn’t be complicated that members of the campaign staff should not be physically assaulting members of the press,” he said. “That shouldn’t be a complicated decision … I will say it’s consistent with a pattern of the Trump campaign.”

Trump stood by his campaign manager — he said surveillance video “exonerates him totally” — and cast it as a trait that would benefit the country.

“I’m a loyal person,” said Trump. “I’m going to be loyal to the country. I’m going be loyal to Wisconsin. We have to tell it like it is.”

Trump said it would be easier to cast off Lewandowski but added that he would not do that. “I’ve fired many people,” he said. “Especially on ‘The Apprentice.’”

Trump was in no mood to back off on his relentless attacks on Cruz. He pounced on a misstatement by the Texas senator, who inadvertently called Florida his home state. “His home state is not Florida,” Trump said. “It’s Texas. It may be Canada.”
