(DCNF)—Harvard Law professor Alan Dershowitz said on Newsmax Tuesday that he will actively campaign for Republicans in the upcoming midterm elections, despite his six-decade affiliation with the Democratic Party.

Democrats are repeatedly attacking President Donald Trump with extreme rhetoric. Former Vice President Kamala Harris called him a “fascist” during the 2024 campaign. Texas Rep. Jasmine Crockett repeatedly compared him to “Hitler.” In an appearance on “The Record with Greta Van Susteren,”  Dershowitz said Democrats embrace political extremism. He also said they abandoned core constitutional principles, a shift that he said left him no choice but to walk away from the party he supported for more than six decades.

“They’re [Democrats] not succeeding in persuading the American people that they’re up to a leadership role, which is why, after me being a Democrat for 60 or more years, I am now going to campaign very hard for the Republicans to maintain control of the House and the Senate. Not because I love the Republican agenda,” Dershowitz told host Greta Van Susteren. “It’s because I’m totally frightened if the Democrats were to gain control of either House. Who they would appoint as chair people? Who they would put in the position of inquisitors, and how they would deny rights to people, and how they would introduce a kind of McCarthyism that we haven’t seen since I was a college student in the 1950s?”

Dershowitz mentioned Democratic Pennsylvania Sen. John Fetterman as one of the few Democrats who still values principle and bipartisanship.

“It’s left-wing McCarthyism. We’re seeing it throughout the Democratic Party with a few exceptions, like the great Senator Fetterman, who you interviewed, who really is the one person who represents principle, represents honesty, and really nonpartisan approaches in the Democratic Party,” Dershowitz said.

Dershowitz said the Democratic Party has veered to the far left.

“I wish his colleagues would learn from him, but they don’t. They are moving toward the extreme, extreme left, and the only thing they care about is trying to hurt President Trump,” Dershowitz added.

CNN senior data reporter Harry Enten said Tuesday that 52% of voters believe Trump is following through on his 2024 campaign promises. Enten said Trump’s steady 43% approval rating reflects voter expectations on key issues like border security, inflation, and crime.

Trump held a 44% approval rating in October 2024, and his support from voters may pose a serious challenge for Democrats heading into the 2026 midterms. Recent surveys show Democrats only slightly ahead in generic ballot matchups, with a New York Times poll putting them up by two points and Yahoo/YouGov showing a four-point edge.
