Former Rep. Ron Paul (R-Texas) said on Thursday he wouldn't vote for Republican presidential front-runner Donald TrumpDonald TrumpUkraine's president compares UN to 'a retired superhero' Collins to endorse LePage in Maine governor comeback bid Heller won't say if Biden won election MORE.
"I was very explicit about that. I wouldn't vote for Donald Trump," he said on CNN on Thursday.
"If you can't stand any of them and you happen to be a dedicated progressive, you ought to make your vote count and vote for the Green Party and if you happen to be a libertarian, vote for the Libertarian Party," he continued.
Paul noted that some people say Trump is "far superior" or the lesser of two evils, but he doesn't know what the celebrity real estate mogul would do if elected president.
"Quite frankly, I'm not sure exactly what he'll do and that bothers me as well," he said, "because he can give two positions in one speech."
Paul, who ran for president in 2008 and 2012, predicted earlier this month that the Republican Party would do everything possible to stop the Trump from securing the nomination.
"The Republican Party is obviously threatened by Trump being his own boss," he said at the time. "Trump's not going to go away easily. ... That's not going to happen. He likes trouble and he doesn't mind threatening people."
