For all of his outbursts, Grayson has been inventive with his slurs. On Wednesday, he bizarrely accused one reporter of being a “s—-ing robot” — a phrase that’s sure to become part of his legacy of incendiary remarks, which include branding a lobbyist a “K Street whore,” likening the tea party to the Ku Klux Klan and accusing a Christian conservative opponent of being a member of the Taliban.

Grayson, who wouldn’t comment on his tirades, didn’t dispute participating in a difficult phone call a few weeks previously with DSCC Chairman Jon Tester, who informed the representative that the committee would likely soon endorse Rep. Patrick Murphy. Grayson denied he directly swore at Tester — as two sources alleged — but he wouldn’t comment on what he said.

“What’s the deal here? You publish whatever colorful lies people toss your way, for their own obvious political purposes?” Grayson asked via text message…

“You’re making a mistake,” Grayson said, likening Murphy to a piece of excrement. “When I’m a senator, it’s going to be hard to work together.”
