LOSING IT: Schumer goes off on Trump supporter at NYC restaurant, witness says.

“They are a highly respected couple, and Schumer made a scene, yelling, ‘She voted for Trump!’ The Califanos left the restaurant, but Schumer followed them outside.” On the sidewalk, Schumer carried on with his fantastical filibuster: “ ‘How could you vote for Trump? He’s a liar!’ He kept repeating, ‘He’s a liar!’ ”

Hilary confirmed the confrontation, telling Page Six, “Sen. Schumer was really rude . . . He’s our senator, and I don’t really like him. Yes, I voted for Trump. Schumer joined us outside and he told me Trump was a liar. I should have told him that Hillary Clinton was a liar, but I was so surprised I didn’t say anything.”

Joe Califano was my boss back at Dewey Ballantine. I’m glad to hear he’s doing well, though the Joe I remember probably wouldn’t have let some punk Senator yell at his wife. And good for Hilary.

But this is pretty much proof that Trump is living rent-free in the heads of the Democratic leadership. His victory really did cause a party-wide nervous breakdown.

UPDATE: From the comments: “Clearly this shows that the Senator from New York may be losing his ability to direct the affairs of state!”

Plus: “People who are confident do not do that in public.” True.
