The Texas senator, who's positioning himself to be the alternative to Donald TrumpDonald TrumpThird-party candidate McMullin: We can win Idaho and Wyoming Pence's plane skids off runway in New York Trump lashes out over 'illegal' Access Hollywood tapes MORE, called on his opponents to unite behind one candidate to take on the GOP front-runner. Both the Florida senator and retired neurosurgeon have yet to win a state.

“If tomorrow morning, a candidate is sitting there and he’s won zero states and doesn’t have a credible shot at getting the delegates, then I do think it’s worth a candidate thinking about coming together and uniting behind,” Cruz said in a Tuesday interview on "The Mike Gallagher Show." 

"I do think what today will do is help narrow the field. We need to get to a one-on-one battle with Donald Trump," Cruz continued.

The Texas senator said he expects to fare well in his home state, where some recent polls show him leading Trump by double digits. Cruz pointed to polls showing Rubio losing to the GOP front-runner in his home state of Florida.

“There is no doubt, if you can’t win your home state, it is a big, big, big problem,” Cruz said. "The polling shows Marco losing his home state of Florida by 20 points; he’s getting clobbered at home." 

"He is a very talented individual, but Marco doesn’t have any viable path to beat Donald Trump," Cruz added. "In the first four states, he’s gone 0 for 4. In all likelihood, he will lose every single Super Tuesday state."

The interview comes as 11 states hold primary contests. Trump is poised to sweep many of those Super Tuesday states and extend his massive delegate lead.
