Donald Trump is poised to dominate Super Tuesday, with only Texas and Minnesota as true contests for Sen. Ted Cruz and Sen. Marco Rubio, respectively. Trump is expected to rake in delegates across the southern Super Tuesday states of Alabama, Arkansas, Georgia, Oklahoma, Tennessee, and Virginia.

In anticipation of Super Trump-day, the Republican establishment is no longer dancing around their distaste for their likely nominee, The Hill reports.

"This would be an epic political moment because it would be the fundamental redefinition of a great political party. It would, in many ways, be a dismantling of it," Peter Wehner, a veteran of the Ronald Reagan, George H.W. Bush, and George W. Bush administrations, told The Hill.

"I am not going to vote for Trump under any circumstances,” Wehner went on. "I see him as an existential threat ... a threat to America and the Republican Party and conservatism unlike anything I have ever seen."

On Sunday, Sen. Ben Sasse (R-Neb.) also expressed his revulsion to voting for Trump, claiming that in a matchup between Trump and Hillary Clinton, he would vote for neither.

"This is a man utterly unfit to be president of the United States and nobody should be pretending otherwise," echoed John Hopkins professor and George W. Bush administration alum Eliot Cohen. "It's just dreadful. And I should be clear, I am a Republican. It's extremely painful."

In the latest poll, released today, Trump holds a massive 40 percent of support among registered Republicans nationwide, lapping Rubio's 21 percent and crushing Cruz's 18 percent, Ben Carson's 8 percent, and John Kasich's 7 percent. The poll by NBC News/SurveyMonkey reached over 4,200 Republicans online between Feb. 22 and Feb. 28. Jeva Lange
