Republican presidential frontrunner Donald Trump would not rule out making a run for president as an independent despite signing a pledge over the summer saying he would support the eventual GOP nominee instead of running a third-party bid.

“I’m going to have to see what happens. I will see what happens. I have to be treated fairly,” Trump said Sunday on ABC’s “This Week” when asked about a new guerrilla effort by operatives within the Republican Party to derail Trump’s candidacy. “When I did this, I said I have to be treated fairly. If I’m treated fairly, I’m fine. All I want to do is [have] a level playing field."

Trump has previously cited "fairness" as a reason he would run a third-party bid. In September, when he signed the pledge, he said he gained nothing besides "assurance that I’ll be treated fairly.”

Trump pointed out that he’s currently content with his position in the polls.

“I’m leading every poll by a lot,” Trump said. “It’s not even a little bit anymore -- it’s a lot.”

Trump also targeted Hillary Clinton, a potential rival in the general election, saying she didn't "have the strength or the stamina" to be president.

"She's not a strong enough person to be president," he said.
