At least one poll says he is, at least for now, the Republican front-runner. One rival has called his candidacy a "cancer." And some, including the editorial board of the Des Moines Register, wish he would just go away — calling for him to drop out of the 2016 presidential race.
But, no matter what you think about Donald Trump, one thing is undeniably true: Almost everyone is talking about him.
For yet another week, Trump talk dominated the Sunday morning political shows, with several devoting roundtable discussions to his disruption of the GOP presidential primary and at least two of his GOP rivals using their clashes with him in recent days as a means of securing interviews on the shows — during which they continued to clash with him.
Of the six GOP candidates (excluding Trump) who appeared on talk shows this morning, at least four were asked directly about Trump.
"I'm not getting into that...I don't have a read on it, I'm not talking him," Ohio Gov. John Kasich told Chuck Todd on NBC's "Meet the Press." "You ever play golf and a guy's ahead after 14 holes, he's still got like five holes to go. So I'm not worried about him."
While several of his rivals were discussing him, Trump spent his Sunday morning calling into CNN's "State of the Union" to blast Hillary Rodham Clinton, boast about the crowds that come to his rallies and claim that leaders of the Republican National Committee are warming up to him.
"They [the RNC leaders)] view me as an outsider, I guess. And now they're starting to view me not as an outsider, because I'm leading in all the polls, not just" CNN's Trump told Jake Tapper. "And I think they have been really nice over the last few days."
But few of those running against Trump have been "nice" in recent days — with candidates decrying his attack on Sen. John McCain's time as a prisoner of war and comments about Mexican immigrants that many viewed as, at best, insensitive and, at worst, racist.
"You can divide the Republican field into three separate pots: those who are trying to be nice to him in the hopes they can pick up some of his crumbs if and when he leaves, those who are silent and just hoping to dodge his bullets, and those who are standing up to him, decrying him and saying he does not stand for Republican values," said Ana Navarro, a GOP strategist and adviser to presidential candidate Jeb Bush, on ABC's "This Week." "Choose your pot."
The focus on Trump provided continued opportunities for some of his GOP rivals, especially those polling poorly, to gain national attention, even if only for continuing to spat with him.
Among those taking to the airwaves on Sunday morning were former Texas governor Rick Perry and Sen. Lindsey Graham, both of whom are polling near the bottom of a crowed GOP field.
"I think he's appealing to the dark side of American politics," Graham (R-S.C.) said on "This Week." "He is not offering solutions to hard, complicated problems. He is basically selling fear and prejudice."
Later in the interview, Graham — who had to get a new cellphone last week after Trump gave out the senator's number at a campaign rally — insisted that the real estate mogul is not qualified to be commander in chief.
"I don't believe Mr. Trump is qualified to be commander in chief." Graham said. "I think he's bankrupt when it comes to the — all the qualities you need to lead the men and women in uniform and to lead a great nation."
Perry, who has hit back aggressively at Trump, told Tapper that concerns about immigration are important to many GOP voters, but that Trump's tone has been incendiary.
"As we have got to see the real Donald Trump, I have got some real problems with that," said Perry, who has previously described Trump's candidacy as a cancer for Republicans. "I think that what he is saying and what he is doing is not necessarily moving the cause of conservatism forward."
Later in the morning, Perry was even more pointed in his criticism, vowing to continue to clash with Trump.
"I want to be very clear that I'm not going to go quietly, as any individual, whether it's Donald Trump or anyone else, lays out concepts that frankly are out of line with the old, historical conservatism," Perry vowed on CBS' "Face the Nation."
But no matter what he says about Trump, the ongoing spat between the two may be paying dividends for the former Texas governor. He is 10th in Republican primary polls — placing him in the last slot in next week's debate and in the bottom third of the field overall. And yet, by engaging with Trump, Perry has ensured that his name stays in the headlines and that he keeps being booked on television. This morning, he was one of just two GOP contender to appear on multiple Sunday shows.
Meanwhile, Sen. Rand Paul (R-Ky.) dodged the bait when he was asked Sunday morning about Trump's seemingly surging campaign, declining to discuss Trump directly when asked by Fox News' Chris Wallace whether the real estate mogul's comments on immigration would hurt efforts to expand the GOP's reach to minority voters.
"My concern is that I want to reach out to new people, go places that no Republican has been going. So I've been to Detroit. I've been to Ferguson [Mo.]. I've been to the South Side of Chicago. I've been to inner-city Philadelphia at a boys' Latin school. I've been trying to go places that no one else is going. I've been to the historically black colleges. I'm going to keep doing that and reaching out." Paul said. "And when I think of immigration, I think that you do have to have a secure border, but I don't automatically think, oh my goodness, that immigrants are bad people. I think the opposite. I think of my great grandfather, who came here from Germany, and I think that most immigrants come here seeking the American dream. And I'm not going to vilify all immigrants with a broad brush."
But no matter what tack his rivals take, it remains increasingly clear that Trump will not go quietly into the night.
"There's a movement going on. This is more than me. This is a movement going on," Trump said on CNN. "People are tired of these incompetent politicians in Washington that can't get anything done. They can't make deals. They can't do anything. I mean, they go and they — all they care about is getting elected. They don't care about anything else."
Recent national polls with him in the lead mean he will be on the stage during the GOP's first primary debate, to be held in Cleveland. And, if he's unsuccessful in the primary, Trump has floated the idea of running a third-party bid.
"This man has got some momentum," Rep. Keith Ellison (D-Minn.) said on "This Week." "And we'd better be ready for the fact that he might be leading the Republican ticket."
The comments prompted laughs from other members of the panel and host George Stephanopoulos to reply: "I know you don't believe that."
