GOP presidential hopeful Donald Trump stopped by Fox News Channel and CNN tonight to threaten to leave the party and run as an independent if he’s not “treated fairly” by Republican establishment.

“If I’m treated fairly, I would never do it.  If I’m not treated fairly, I might very well do it,” he told Bill O’Reilly on FNC.

To CNN’s Don Lemon, Trump said a split with the GOP is “highly unlikely, unless they break the pledge to me.”

“It’s a two way street. They said they will be honorable,” Trump told Lemon, adding ominously, “So far, I can’t tell you if they are, but the establishment is not exactly being very good to me.”

Asked to elaborate, Trump said, “I’m leading in every poll – by a lot. It looks like I’m going to win. My whole life has been about winning. I’m not like so many of the other people that you to talk to that are essentially losers, okay? I know how to win. I intend to win. It’s ‘the best way of beating the Democrats if I get the nomination.”

Lemon naturally asked Trump to define being treated not fairly.

“If they don’t treat me with a certain amount of decorum and respect. If they don’t treat me as by far the frontrunner. If the playing field is not level, then certainly all options are open,” Trump said. “We’ll go through the primaries we’ll see what happens and I’ll make a determination.”

One day earlier, OReilly forecast Trump’s new plan to bar Muslims from coming to this country had “pretty much sealed his doom within the party itself.”

“The chieftains who run the party, who are loathed by many Republican conservatives” will “say there is no way we’re going to give him the nomination” and he won’t win enough delegates outright, O’Reilly predicted.

Trump already had signaled yesterday he might go rogue,after House Speaker Paul Ryan blasted Trump’s Muslim ban plan. “This is not conservatism,” Ryan decried, adding that it did not represent the GOP’s values. Trump’s Nuts-To-You response on Twitter: “A new poll indicates that 68% of my supporters would vote for me if I departed the GOP & ran as an independent.”

Tonight O’Reilly put his theory to Trump.

Trump didn’t like it.

“I think I will get the delegates,” the candidate shot back. “I have found the [GOP] establishment has not been as smart as people thought. We have to do the right thing and be truthful and say what the problems are, and that’s what I’m doing and that’s why I’m winning.” Trump’s Muslim-ban plan has been blasted by nearly every other GOP candidate.

To implement his plan, “I would set up a very strong system… It’s a temporary ban on not everybody, but many,” Trump explained to O’Reilly. “I would set up a system to see who qualifies to come in, who doesn’t, until we come down with the answer.”

Scolded the FNC host: “I don’t think you’ve thought through the unintended consequences about banning a whole religion.”

“I’ve thought through everything, believe me,” Trump shot back. “And, again, I’ve had calls from my friends who happen to be Muslim, saying, ‘you’re the only one with the courage to say it.’ They all know what I’m saying is true.”

Asked to comment on Hillary Clinton’s assertion Trump’s plan would help ISIS recruit new followers, Trump sputtered,

“Hillary Clinton’s a joke. I’ve been watching her for years. She’s the one that caused the problems, between her and Obama, with their policies. She’s a big factor in this, and then I hear her holier-than-thou” rhetoric, he scoffed. “Hillary’s going to lose.”
