"Now I’ve met much tougher people than Ted Cruz, he’s like a baby compared to some of the people I have to do...he’s like a little baby, soft weak little baby by comparison," the real estate mogul said. "But for lying, he’s the best I’ve ever seen.”
Trump -- who has attacked Cruz's characterizations of his positions on abortion and gun control among others and threatened to sue him -- continued hitting Cruz, saying he expects to win Texas now that Cruz has "exposed himself...he's gonna go way down in Texas."
Cruz responded to Trump's newest remarks by saying that they show how "rattled" he is. When asked by ABC News if he still respects Trump, Cruz said he wouldn’t gamble his daughters' futures on Trump and he “doesn’t know what the heck he would do” if he were president.
"Every day he tosses out a new insult, but the more rattled he gets the more he loses control and the more he engages in just personal attacks," he said. "I have no intention of responding in kind."
But even as Trump continues to attack Cruz, he is keeping his eye on Sen. Marco Rubio -- though holding back from attacking the Floridian.
“I’ve been very nice to him because he hasn’t hit me -– when he hits me –- we’ll see what happens," Trump said. "When he hits me ugh he’s gonna be hit...I hope he does, it’s more fun.”
Trump focused his rally on tonight’s caucuses, asking the crowd in Sparks this afternoon if his supporters knew they’re plan for today.
"We’re down to crunch time folks we gotta do it, like at 5:30 today you know where you’re gonna be?” and with his question, the Donald offered some advice: "And watch out for dishonest stuff because I’ll tell you what a lot of dishonesty with this you just gotta be careful they have paper ballots, whole deal going.”
Trump's lawyers sent a letter to the Nevada GOP questioning an alleged request of the Cruz campaign for their supporters to film voting tonight.
Earlier today the Nevada Republican Party ordered no filming at caucus locations.
