Harvard Law professor Alan Dershowitz warned the Democratic Party it’s going to lose his support as well as the midterm and presidential elections if candidates like Alexandria Ocasio-Cortez and Bernie Sanders keep winning.

“I won’t let the Democrats steal my party from me. I want to regain the center,” Dershowitz told WABC Radio’s “Curtis and Cosby” show Tuesday.

“I want to make sure that the radical Left, the woman who got elected in the Bronx and Queens to Congress on the Democratic ticket, that they and Sanders and others don’t represent the Democratic Party. I want a fight within the Democratic Party to restore it to the days when it was a great centrist party, when it united people rather than divided people,” he added, referring to socialist Ocasio-Cortez pulling off a stunning defeat of incumbent Democratic Rep. Joseph Crowley, a 20-year veteran of Congress, in last week’s primaries.

Despite being a staunch defender of President Trump, Dershowitz says he isn’t yet planning his exit from the Democratic Party.

“I will remain a Democrat as long as there’s some chance the Democratic Party can return to normalcy,” Dershowitz said.

Also in contrast with his party, Dershowitz said during an appearance on “Fox and Friends” earlier Tuesday that he hopes Trump nominates a “true conservative” to the Supreme Court. Trump has yet to announce his pick, something he said he would do on July 9, but Democrats have already pledged to block his nominee until after the 2018 midterm elections.
