Republican presidential hopeful Ted CruzTed CruzRepublicans giving Univision the cold shoulder: report How 'Big Pharma' stifles pharmaceutical innovation AIPAC must reach out to President Trump MORE said all of the GOP candidates are now going after him instead of front-runner Donald TrumpDonald TrumpCombating opioid epidemic, repealing ObamaCare will hurt the cause Money doesn't buy elections and elections aren't rigged.

"Six weeks ago, everyone was shooting at Trump," he said Sunday on NBC's "Meet the Press." "Now all the Republican candidates are shooting at me. That reflects a change in this race."
Cruz said that Trump thought he was "terrific" just six weeks ago. But, he said, when Cruz started to gain in the polls, Trump blasted him with personal insults.
Cruz said he plans to focus on policy and record — and who will be a consistent conservative. He said he doesn't plan to respond to people with insults, adding that both Trump and Marco RubioMarco RubioRepublicans giving Univision the cold shoulder: report Week ahead: Senate panel to vote on Trump's Labor pick Senators introduce new Iran sanctions MORE are attacking him "with all their might."
"And we're drawing contrasts. And the contrasts are clear. And the contrasts, by the way, are substantive and policy based," he added.
Cruz also said the most common sentiment he hears from people is that they're frustrated with Washington and politicians who say one thing and do another.
"The reason that I see conservatives uniting behind our campaign is they're looking for a consistent conservative," he said. "Someone they can trust to be a fiscal conservative, a social conservative, a national security conservative."
Cruz went on to criticize both Trump and Rubio for their positions on amnesty and healthcare. He said that that a vote for Rubio is a vote for amnesty and a vote for Trump is a vote for ObamaCare to make it socialized medicine.
"If you look at their positions, Marco Rubio right now as a presidential candidate is advocating amnesty, advocating citizenship for 12 million people here illegally," he said. "And Donald Trump, right now as a candidate, is advocating full on expanding Obamacare."
He also said Trump and Democratic presidential candidates Bernie Sanders and Hillary Clinton have the same position on healthcare.
"They want to put the government in charge of you and your doctor," he said.
