Trump: Bush Should Quit, Carson Isn't Qualified, and Rubio Is 'Weak'

GOP front-runner Donald Trump had tough words Tuesday for three of his major competitors for the presidential nomination, but his toughest ones came for Jeb Bush, who he said should "absolutely" drop out of the race.

"He doesn't have a chance," Trump told ABC's "Good Morning America" host George Stephanopoulos. "Look, Jeb is a nice guy [but] he's a stiff. He ought to do what [Wisconsin Gov. Scott] Walker did."

Bush on Monday went after Trump, commenting that the solution to solving the country's woes won't be found in someone like Trump, "who has never demonstrated the capacity to implement conservative ideas. And you can't just tell Congress, you're fired and go to commercial break. "

Bush has several million in his campaign coffers, Trump acknowledged on Tuesday, but still, he's "wasting his time" and "a lot of money."

But his comments also reached to retired neurosurgeon Ben Carson, who is on top in some national polls, and to Florida Sen. Marco Rubio.

Making deals, said Trump of Carson, is "not his thing. He doesn't have the temperament for it. I think Ben just doesn't have the experience."

And when it comes to Rubio, Trump said he's "not a fan" and he thinks the younger man is "overrated" and "a lightweight."

When Bush commented on Rubio's voting record during the debate, the message was "horrible" the way it was delivered, said Trump, but Rubio's further problems will center around his changing stance on immigration.

"He was a member of the Gang of Eight, … All of a sudden, his poll numbers went down and he got out of the Gang of Eight," said Trump. "He's very weak . . . [Russian President Vladimir] Putin would eat him alive."

Also on the program, and in an interview on Fox News' "Fox & Friends," Trump continued his complaints about recent debates, telling Stephanopoulos that "we're being asked very rude questions, many of them directed at me."

However, he said he will not be joining forces with a group of candidates who met on Sunday to collectively seek changes in upcoming debates, as he chooses to negotiate directly with debate hosts himself.

"I love the debates," he told "Fox & Friends." "I have never debated before and I like the debates. They really serve a great function."

But the debates are done unfairly, he maintained, and Hillary Clinton, who he thinks will be the eventual Democratic nominee, was thrown "softballs" in her debate.

"It was very well orchestrated," he said. "They don't want anything to happen to her that's going to be bad, and they didn't hit her with one question."

Trump on the shows also talked about his new book, "Crippled America: How to Make America Great Again," telling "Fox & Friends" that the book speaks to the trouble the country is under, blaming it on poor leadership.
