Former Texas Rep. Ron Paul is no fan of what Donald Trump is doing in the presidential race, citing his "aggressive personality" during an interview with Newsmax TV. Paul, who ran for president three times, tells "The Hard Line" host Ed Berliner he is concerned about Trump's "take charge and take over" ideas.

"What I fear is that he may be tapping in to something in a sentiment and the people may love this aggressive personality that's going to take charge," Paul says. "That worries me a little bit, but yes, he's tapping in to a lot of feelings. When he talks about borders, and different things like that and the terrible condition of the economy."He taps in to a lot of people, but the thing that concerns me is that it's sort of like take charge and take over and we've had too much government taking charge and taking over and it's the government that created it and we don't need somebody with an iron fist to come in and say, 'It'll be done my way and I can correct all these problems,' because the solution isn't to have somebody strong to tell us what to do, what we need is enough people to have confidence in themselves and let the people make their own decisions."Trump told Newsmax TV he would make Mexico pay for a wall to be built between the U.S. and Mexico if he becomes president. In another interview, Trump vowed to "bomb the hell" out of the Islamic State (ISIS).that the stock market's "day of reckoning" is near, and whether Trump — a successful businessman — is the guy to fix it."I don't think anybody should be running the economy and that's the whole fallacy of our last hundred years," Paul says. "[Trump] can't run the economy, he can't create jobs, and he should know that. He can create jobs if he stays in the building industry, but even his industry is going to be in trouble because he might build too many buildings because interest rates are zero."The interview also touched on same-sex marriage in the wake of the Supreme Court's decision to make the practice a constitutional right for all Americans.Paul thinks if people of the same gender want to get married "that's their business.""That's the wonderful thing about libertarianism," Paul says. "It doesn't have to make that final decision of what people should do."
