Former GOP nominee Mitt Romney, who has been a frequent critic of Donald Trump, said there is a real chance Trump could win, calling Hillary Clinton an “awful candidate,” BuzzFeed News reported Friday.

In an interview on the Radio Free GOP podcast recorded earlier this month, but surfaced by BuzzFeed News on Friday, Romney said that it’s “very possible” Trump wins if Clinton has an “implosion.”

“To be honest, it’s very possible in my view that Trump wins,” Romney said. “I wouldn’t think it’d be by a landslide, but I think he could win. I think he could lose, I think he could lose by a landslide. But, I don’t know which it’s going to be and a lot of that depends on what happens to Hillary Clinton. Is there a meltdown moment, or some implosion of some kind?”

The former GOP nominee went on to say that he finds Clinton inauthentic, and that she is attempting act like her husband, former President Bill Clinton, in order to gain votes, calling her an “awful candidate.”

“You can’t forget that Hillary Clinton is a player as well, and she’s an awful candidate. People don’t trust her, they don’t like in my view she comes across as not being at all authentic,” Romney said.

“There are serious women leaders who don’t go into an audience and put their arms up in the air and make a big guffaw kind of smile,” he said. “It’s almost like she’s acting like she’s Bill Clinton and she’s not Bill Clinton. Nonetheless, it doesn’t come across well.”

Romney said he will still not vote for Trump or Clinton and would write in another Republican’s name if he doesn’t like the choices of third-party candidates.
