I remember Alan Dershowitz defending OJ Simpson in the “Trial of the Century” decades ago. I also remember that there was no liberal cause he didn’t or wouldn’t champion. Now, this….
For nearly seven decades, prominent attorney and Harvard Law professor Alan Dershowitz was a registered Democrat. However, citing a profound divergence in values, Dershowitz publicly severed ties with the party—first registering as an independent in late 2024 before officially joining the Republican Party in April 2026. In his book, Why I Quit the Dems: And So Should You!, Dershowitz elaborates on the rationale behind his departure and makes the case for why like-minded voters should follow his lead.
His critique centers on three primary arguments about the modern Democratic Party’s ideological and institutional direction.
Shift Toward Radicalism and Departure from the Center
Dershowitz characterizes himself as a traditional, centrist liberal and an avowed “anti-radical.” In his view, the contemporary Democratic Party has abandoned the moderate, classic liberal principles of the John F. Kennedy era in favor of far-left politics.
He contends that party leadership has capitulated to progressive radicals, pointing specifically to influential figures such as Alexandria Ocasio-Cortez, Bernie Sanders, and Zohran Mamdani. Dershowitz argues that these factions have been allowed to disproportionately dictate the party’s platform, driving it away from its historic, broad-tent foundation.
Israel and Foreign Policy
A central catalyst for Dershowitz’s departure is his assessment of the party’s foreign policy, specifically regarding the Middle East. Dershowitz has described the modern Democratic Party as the “most anti-Israel party in U.S. history.”
He criticizes Democratic leadership for failing to sufficiently marginalize and denounce anti-Zionist, pro-Hamas, and anti-Israel rhetoric emerging from within its coalition. According to Dershowitz, the party has neglected its long-standing commitment to a bipartisan pro-Israel consensus while failing to adequately address the rise of domestic antisemitism.
Civil Liberties and ‘Lawfare’
As a lifelong civil libertarian, Dershowitz claims that the Democratic Party has retreated from essential constitutional safeguards, most notably the First Amendment’s protections of free expression and the Fifth and Sixth Amendments’ guarantees of due process.
Specifically, Dershowitz raises two major constitutional concerns:
- The Weaponization of the Justice System: He accuses the party of engaging in “lawfare”—the use of the legal apparatus for partisan objectives. He points to the criminal prosecutions against Donald Trump as a primary example, describing them as distortions of standard legal norms and the rule of law.
- Double Standards in Free Speech: Dershowitz asserts that the party adheres to a selective view of free expression (“free speech for me, but not for thee”). He argues that institutions aligned with the party, particularly universities, enforce rigid speech codes in some contexts while tolerating hostile and extreme rhetoric against groups they disfavor.
The Case for Leaving the Party
Dershowitz contends that traditional, classic liberals who prioritize due process, robust free speech protections, and strong support for Israel no longer have a political home within the Democratic Party. To Dershowitz, remaining aligned with the party lends tacit approval to its current trajectory. He urges voters who share his foundational principles to exit the party, arguing that a coordinated departure is the only effective way to signal to leadership that weaponized legal strategies and far-left policies carry severe political consequences.
