Kentucky Sen. Rand Paul, who is running for the Republican presidential nomination, continued his war of words with Donald Trump on Friday.

Speaking with The Hard Line on NewsMaxTV, the Kentucky senator said Trump -- who called Paul "truly weird" at one point -- is the worst candidate to be the party's nominee.

"Do you think women are going to nominate some guy who judges people by their appearance and calls another candidate ugly? Do you think they're going to nominate somebody who implies that most Hispanics are rapists and drug dealers? 'Oh yeah there might be a few of them who are not,'" Paul said.

"We'd get just swamped in a landslide," Paul, who is currently struggling in the polls and fundraising efforts, argued of the Republican Party if Trump was the nominee.

The Kentucky senator said Republicans will wake up one day and freak out at the prospect of Trump being the nominee.

"The majority of Republicans will wake up and say, 'oh my goodness, we can't nominate this. This would be a disaster for our party and for the country,'" Paul said.

"He's the worst nominee that we could possibly think of and part of the reason is he's not really a Republican," Paul said of Trump, citing the businessman's past support for liberal policies.
