Conservative columnist George Will is calling on the GOP to keep Donald TrumpDonald John TrumpAccuser says Trump should be afraid of the truth Woman behind pro-Trump Facebook page denies being influenced by Russians Shulkin says he has White House approval to root out 'subversion' at VA MORE out of the White House, even if he wins the nomination.

“Donald Trump’s damage to the Republican Party, although already extensive, has barely begun,” Will wrote in a new Washington Post column Saturday.

Will warns a Trump nomination would create “down-ballot carnage” that could end Republican control of the House.

“At least half a dozen Republican senators seeking reelection and Senate aspirants can hope to win if the person at the top of the Republican ticket loses their state by, say, only four points, but not if he loses by 10,” Will wrote, saying Trump would be the most unpopular nominee ever.

He calls on voters in upcoming primary states, Indiana and California, to vote for Ted CruzRafael (Ted) Edward CruzOvernight Health Care: Trump eases rules on insurance outside ObamaCare | HHS office on religious rights gets 300 complaints in a month | GOP chair eyes opioid bill vote by Memorial Day HHS official put on leave amid probe into social media posts Trump, Pence to address CPAC this week MORE, to “make the Republican convention a deliberative body rather than one that merely ratifies decisions made elsewhere, some of them six months earlier.”

“A  convention’s sovereign duty is to choose a plausible nominee who has a reasonable chance to win, not to passively affirm the will of a mere plurality of voters recorded episodically in a protracted process.”

He adds, however, that if Trump wins the nomination, the GOP should work instead toward cutting presumptive nominee Hillary ClintonHillary Diane Rodham ClintonWoman behind pro-Trump Facebook page denies being influenced by Russians Trump: CNN, MSNBC 'got scammed' into covering Russian-organized rally Pennsylvania Democrats set to win big with new district map MORE’s term to four years.

“If Clinton gives her party its first 12 consecutive White House years since 1945, Republicans can help Nebraska Sen. Ben Sasse, or someone else who has honorably recoiled from Trump, confine her to a single term.”

Will has been a constant critic of Trump throughout the campaign, saying previously his nomination would be the “end” of the Republican party.

Trump has shot back at Will, accusing him of being “biased.”

“Broken down political pundit @GeorgeWill, who is wrong almost all of the time, should be thrown off @FoxNews. Boring and totally biased,” Trump tweeted in November.
