Trump said that the party leadership has resisted his candidacy because he entered the race as a political outsider. But he added: “I think it’s coming together.” He said that the party will need to unite if it does not want to give Democrats the White House in November.
“One thing I’ll say about the Democrats, to a much greater degree, they stick together. They stick together, much more so than the Republicans,” Trump said. “We have the better ideas. And my ideas are better than any of them.”
Trump continued his knocks on hesitant Republicans during a campaign event in Moon Township, Penn., later Saturday afternoon.
"I'd like to see Republican leadership be very strong, very smart," Trump said. "And you got to be cool."
He added: "We are going to win, either way."
Trump recycled attacks against former Republican presidential nominee Mitt Romney, who has remained critical of the real estate mogul’s tone and temperament. Romney hosted an annual summit in Park City, Utah, over the weekend where concerns over Trump were a dominant theme, prompting more critiques from Trump.
“I watched this poor, sad Mitt Romney this morning,” he said, launching into a mocking impression of Romney. “I don’t think he knows what misogynist is. He’s sitting like a real stiff.”
“We had a candidate that didn’t work like he should’ve worked,” Trump added later.
Trump interlaced his speech with attacks against Clinton’s judgment, saying that her vote for the Iraq War and push for interventions in Libya and Syria as secretary of state should disqualify her. He repeated a debunked claim that he opposed the Iraq War from the beginning.
“When crooked Hillary says ‘Donald Trump temperament.’ She’s got the bad temperament,” Trump said. “Remember what the Secret Service agent said: 'She’s a total mess, she’s unstable, and she can’t be president.’”
He was referring to accusations published in a book by a former Secret Service agent about Clinton's behavior.
Trump also attacked Clinton for using a private email server as secretary of state, accusing her of compromising national security.
The Republican candidate also went after Sen. Elizabeth Warren (D-Mass.), who political observers think could become Clinton’s running mate. Trump has mocked her Native American heritage in recent weeks, regularly referring to her disparagingly as “Pocahontas.” He joked about apologizing for the comparison in Tampa on Saturday — to Pocahontas herself.
“I said yes, I will apologize: to Pocahontas. To Pocahontas I will apologize, because Pocahontas is insulted,” he said.
Trump also mocked Secretary of State John F. Kerry, who injured himself last year in a bicycle accident. Trump said that Kerry’s injury was an embarrassment for the United States during diplomatic negotiations with Iran.
“He goes into a bicycle race, and he breaks his leg, and he’s incapacitated,” Trump told the crowd, which laughed along. “And you know what they’re saying to each other? 'How dumb is this guy? How dumb?’”
