Jimmy McMillan, the whiskered political showman who became a viral Internet star when he ran for governor of New York in 2010 as a candidate of the Rent Is Too Damn High Party, has announced his retirement from the political arena, citing a lack of public support for his agenda.

In a news release infused with misspellings and other errors that was dated Tuesday, Mr. McMillan said voters had been “totally brainwashed” and criticized Gov. Andrew M. Cuomo and Mayor Bill de Blasio, both Democrats, for not securing “a rent reduction for the people in the cities of Brooklyn, Bronx, Staten Island, Manhattan and Queens.”

“Rent is too damn high is an international crisis,” he wrote. “There are many questions the people should ask themselves. I which them the best — I’m out.”

The news release said the Rent Is Too Damn High Party was “for sale, trademark and all,” and listed a Manhattan lawyer, Vincent Imbesi, as a point of contact.
