Republican Ted Cruz jumps seven points into second place – Reuters/Ipsos poll

After Cruz continued to deny the disparity, maintaining that he wanted to kill the Rubio-sponsored bill, Baier asked: “The problem is at the time you were telling people… that this was not a poisoned bill”.

US Republican front-runner Donald Trump defended his provocative call for banning Muslims from the United States in Tuesday night’s presidential debate as the candidates pushed their own plans for fighting Islamic State in Iraq and the Levant (ISIL) militants. My question to you is: “looking back at what you said then and what you are saying now, which one should people believe?” Ted Cruz (R-Texas) on Wednesday over his questioning of presidential rival Donald Trump’s “judgment”. Indeed, I led the fight against his legalization and amnesty.

“He clearly was a support of legalization”, Rubio told Fox host Megyn Kelly. Bernie Sanders of Vermont, businesswoman Carly Fiorina, Carson, Cruz, former House Speaker John Boehner, Rubio, former President Jimmy Carter and new Canadian Prime Minster Justin Trudeau.

“I think Ted Cruz needs to be clear about what his stance is today on that, but I can tell you what it’s been in the past”, Rubio said.

Later, in Minnesota on Thursday, Cruz said that Rubio had broken the vow he had made to the voters who elected him in 2010.

This week’s Republican debate did little to scramble the GOP presidential horserace, according to the first national poll fielded since the showdown.

Baier quoted Cruz, in audio leaked to The New York Times, saying that the question of national-security “judgment” would ultimately be “challenging” for Trump.

Throughout the campaign Senator Rubio has argued that Senator Cruz’s support for the USA Freedom Act, has dangerously limited the program, which was revealed by Edward Snowden.

After that it gets tricky, unless you’re Donald Trump. “They were not telling the truth”, he said.

Cruz asserted “I have never supported legalization”, despite having introduced legislation that would have extended legal status to millions who are in the country illegally. “We beat it”, Cruz said. “And I think the lion’s share of their supporters come to us”.

“Now, Marco Rubio is a friend of mine he is a wonderful communicator, he’s a charming individual he’s very well liked”, Cruz said.

All the other candidates are afraid to take on Trump, because they don’t want to lose his followers.
