Harvard law professor and constitutional attorney Alan Dershowitz has officially ditched the Democrat Party after 67 years and registered as a Republican.

In a powerful Wall Street Journal op-ed published Monday, Dershowitz blasted today’s Democrat Party as increasingly hostile toward Israel and dangerously consumed by radical ideology, warning that its current trajectory poses a serious threat to the country.

Over the past year, Dershowitz repeatedly warned that Democrats were abandoning core American values. He even pledged to campaign for Republicans in the 2026 midterms, saying he was “totally frightened” by the prospect of Democrats regaining power.

“I’m going to be supporting the Republicans in the midterm election. I’m hoping that the Republicans maintain control both of the House and the Senate,”

“The last thing I want is Chuck Schumer to be head of the Senate or Liz Warren to be chairperson of a committee or AOC to be chairperson of a committee.”

“The Democrats have not only lost my votes, but they have made me an enemy, essentially, by how they’ve moved away from American values, Israeli values and values of decency,” he continued. “I’m not a Republican, but I am a very anti-Democrat. I’m against the Democratic Party. I will do anything to see Mamdani defeated.”

On Monday, Dershowitz officially left the Democrat Party.

I am a lifelong Democrat. I started campaigning for the party’s local candidates as a teenager in Brooklyn, N.Y., have been a registered Democrat for 67 years, made speeches for John F. Kennedy as a college student, and can count on one hand the number of Republicans I’ve ever supported for any office.

I still disagree strongly with the GOP on abortion, the separation of church and state, immigration, healthcare and taxes, among other things. Yet I’ve decided to bite the bullet and register as a Republican.

I believe that the Democratic Party’s hostility to Israel represents a deeper and more dangerous shift away from the center and toward a radical approach that is bad for America and the free world. So I intend to work hard to prevent the Democrats from gaining control of the House and Senate, and I urge those who share my concerns about the increasing influence of radicalism in the Democratic Party to vote, campaign and contribute for continued Republican control of Congress. I will contribute money to Republican candidates, campaign for them, make speeches at Republican events, and urge pro-Israel Americans to change party affiliation or at least vote against Democrats. Until something changes, I will vote Republican for representative, senator and president.
