For me that train has already left

Dershowitz unloads on NY socialist Dem, Martha's Vineyard liberal

“I won’t let the Democrats steal my party from me. I want to regain the center. ...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.”

The Democratic Party is never coming back. There may be a Party someday for some Blue Dog Democrats but that will be them breaking off from the radical Left. And that would be a huge gift to Republicans. ...I'm never going back.
