FORT MYERS, Fla. — His party in disarray, a surging Donald Trump called on mainstream Republicans to unify behind his candidacy on Wednesday as his White House rivals pursued their last best opportunity to block the billionaire businessman from building an insurmountable delegate lead in two key states.
The often-brash Trump softened his tone, at least temporarily, hours after securing three more primary victories, praising House Speaker Paul Ryan as a man he respects and encouraging Mitt Romney to promote party harmony. As for his own campaign, he said he's poised to score a knockout in next week's winner-take-all primaries in Florida and Ohio.
"If I win those two, I think it's over," he told CNN's "Anderson Cooper's 360."
"Instead of fighting it, they should embrace it," he added on Fox News Channel. "If we embrace what's happening and if everybody came together ... nobody could beat the Republican Party."
Still, amid growing resistance to Trump's insurgent campaign, a number of former GOP presidential hopefuls have re-emerged in support of his current rivals.
Former Florida Gov. Jeb Bush planned to confer with all the candidates — save Trump — ahead of Thursday's GOP debate. He was meeting privately with Florida Sen. Marco Rubio on Wednesday, and planned to meet with Texas Sen. Ted Cruz and Ohio Gov. John Kasich on Thursday, said Kristy Campbell, Bush's former campaign spokeswoman. She provided no details.
Bush and Trump engaged in heated confrontations throughout Bush's campaign, repeatedly referring to each other as a "loser."
Rubio took Bush's attacks a step further in recent weeks, poking fun at Trump's tan, hair and hand size. Now, in the midst of a weeklong march through Florida to save his candidacy, Rubio concedes he made a mistake.
