How Radical Democrats Drove Dershowitz to Become a Reluctant Republican

For nearly seventy years, Alan Dershowitz remained a loyal Democrat—until, in his view, the party abandoned its centrist foundations and embraced radical hostility toward Israel. Reluctantly, he aligned himself with the Republican Party despite continuing disagreements with parts of its domestic agenda. In an era marked by deepening division and ideological extremism, his overriding concern became preventing the rise of politicians and movements he believes threaten democratic institutions and civic stability.

He observed for years what he saw as a growing shift toward left-wing extremism, particularly on university campuses, and sought to challenge it from within the Democratic Party as a loyal dissenter. But after October 7, 2023, Dershowitz concluded that the transformation of the party had become irreversible—especially regarding Israel and its supporters. Remaining affiliated with a movement he believes now tolerates or promotes ideological extremism, he argues, would betray principles he has upheld throughout his life.

Yet his political break is neither simple nor absolute. Alan continues to support many traditionally liberal positions, including reproductive choice, gay rights, environmental protection, racial equality, and expanded access to health care, while opposing policies he views as anti-meritocratic, such as race-based affirmative action and DEI initiatives. Had the Democratic Party not, in his opinion, dramatically shifted against Israel, he believes he might well have remained what he calls a “Fetterman Democrat.” Instead, he describes the party’s increasingly strident anti-Israel stance—even among self-described centrists—as the final rupture that compelled his political realignment.
