A Queens political activist was shot dead in the passenger seat of a Mercedes-Benz Wednesday, ­police sources said.

Jerwaine Gorman, a co-founder and board member of the South East Queens County Young Democrats, was shot by a gunman who walked up to the car at 167th Street near Linden Boulevard in Jamaica and fired a single round at 12:30 p.m., police said.

A woman sitting in the driver’s seat was not harmed, police said.

Lifelong friend Adrienne Felton, who founded the Democratic group along with Gorman, said the activist was “all about uplifting the community.”

No arrests have been made.
