Bad news for those few who imagined Donald Trump would quietly accept the GOP handing the party's nomination to someone else and support a non-Trump candidate.

The Republican front-runner told CNN's Anderson Cooper he no longer promises to support whoever ends up being the Republican nominee during a town hall in Milwaukee Tuesday.

"Do you continue to pledge to support whoever the Republican nominee is?" Cooper asked.

"No, I don't anymore," Trump replied.

Back in September the mercurial mogul signed a pledge promising to to back the eventual Republican nominee, even if the unthinkable happened and that nominee was someone he doesn't see in the mirror every morning.

At the time Trump said, "I have no intention of changing my mind," and "I see no circumstances under which I would tear up that pledge."

That position has now, um, evolved and Trump's new view is that his support is conditional on who ends up being the eventual nominee.

"I'll see who it is," Trump said. "I'm not looking to hurt anybody. I love the Republican party."

Trump explained he was rescinding his vow because he feels he has been "treated very unfairly" by "the RNC, the Republican party, the establishment."

The billionaire businessman said a lot of people would be upset if he was deprived of the nomination.

"When somebody goes in and wins the election and gets less delegates than the guy that lost, I don't think that's right," he added.

As for Ted Cruz and other Republican candidates waffling on their support of him he if were to become the Republican standard bearer, Trump says he could care less.

"He doesn't have to support me," Trump said of Cruz. "I have many many more delegates than him."

"Look I beat these people badly," Trump said. "I don't want to make people uncomfortable. I don't need their support."

Trump wasn't the only candidate to ditch the loyalty oath during the CNN town hall.

Ted Cruz was quite clear that he would not support Trump for president. "I'm not in the habit of supporting someone who attacks my wife and my family," Cruz said. "I think nominating Donald Trump would be an absolute trainwreck. I think it would hand the general election to Hillary Clinton."

John Kasich said he wants to "see how this thing finishes out" before promising to back anyone. Kasich said he still hopes his campaign, "the little engine that can," keeps going and he becomes the one the other candidates rally to support.

"Frankly, all of us shouldn't have even answered that question," Kasich said of the loyalty oath. "I've got to see what happens. If the nominee is somebody that I think is really hurting the country, and dividing the country, I can't stand behind him."
