Donald Trump returned to labeling his ideological opponents with various nicknames Saturday during a rally with Kansas gubernatorial candidate Kris Kobach in Topeka.

Trump said he has been "dreaming" of the various Democrats he sees as "possible candidates."

"I see those candidates before my eyes every night before I go to sleep," he said.

Trump blasted Sen. Cory Booker (D-N.J.) and said he was extremely detrimental to Newark while he held the mayorship prior to getting elected to Congress.

Trump again referred to Massachusetts Democratic Sen. Elizabeth Warren as "Pocahontas," a reference to the fact she has claimed to be of partial Cherokee ancestry.

"I've got more Indian blood in me than Pocahontas, and I have none," Trump said.

"Hey, I have high cheekbones too, maybe I'm Indian," he added.

Trump also responded to a 2016 remark by then-Vice President Joe Biden in which he appeared to offer to fight Trump.

"I'd like to take him behind the gym," Biden said while making a speech near his hometown of Scranton, Pa.

"Remember he challenged me to a fight?" Trump recalled. "I'd love that."

Trump then turned his attention to Sen. Richard Blumenthal (D-Conn.), who was a vocal opponent of Trump's decision to nominate Justice Brett Kavanaugh.

Trump repeatedly called Blumenthal "Da Nang Dick" -- in reference to the Vietnam port city -- adding that the senator misrepresented his military service during the Vietnam War.

"He's a fraud, he was never in Vietnam," Trump said, adding that the fact Connecticut elected Blumenthal shows that the Constitution State is "such a mess right now."
