"I have to say it is interesting seeing Donald Trump, you know, just apparently melting down. He seems to be taking losing really badly," Cruz said during an interview with "The Sean Hannity Show" on Wednesday. 
Cruz's comments come after Trump accused the Texas Republican of committing voter fraud because Cruz's campaign erroneously suggested Ben Carson was dropping out of the race during the caucuses. 
Cruz apologized, saying his campaign should have sent out a follow-up report clarifying that Carson wasn't dropping out. 
While Cruz has gotten criticism from both Carson and Trump, he dismissed the fallout over the reports as "silliness." 
"For Trump, he has to blame someone, something, anyone other than himself and his own record for his loss," he said. "It's all designed to be a distraction." 
He added that he understands Trump is "angry" for losing Iowa but said he "told the people of Iowa he thought they were stupid." 
"He skipped their debate," he said. "It makes me wonder if Donald's next step is he intends to tell the people of New Hampshire he thinks New Hampshire is stupid. If he intends to skip their debate." 
Trump skipped a Fox News debate over a long-standing feud with the network. Instead, he held a fundraiser for veterans' groups in Iowa at the same time. 
Cruz suggested Trump was afraid of moderators, and again offered to debate him one-on-one. 
"[It] will be interesting to see if Donald is still afraid of having his record questioned," he said. 
The latest skirmish between Cruz and Trump comes as the two are battling for the top spot in the New Hampshire primary, with Trump having a sizable lead.
