An especially snide politics-watcher has launched a new campaign for our jet setting mayor: “de Blasio for Resident.”

Campaign literature began to pop up on lampposts in Midtown Friday, with a tongue-in-cheek message declaring de Blasio “MISSING,” amid his longshot quest for the Oval Office.

“Last seen embarrassing himself in Iowa, New Hampshire and South Carolina,” read the black-and-white posters. “If seen please tell him to immediately return to New York and do the job he was elected to do.”

The poster — printed with a photo of Hizzoner and his age, height and weight — asks anyone with “information about this man’s whereabouts” to contact “deblasioforresident@gmail.com.”

The poster’s creator, Jason Selvig, told The Post he launched the campaign in an effort to convince the mayor to step away from his 2020 White House bid — amid various polls showing him at zero percent.

“I want to use this platform to formally ask Bill de Blasio to use his CNN town hall on Sunday night to withdraw from the presidential race and to apologize to New Yorkers on live television for the embarrassment he has caused to the city with his disastrous campaign,” Selvig said.

As of Saturday at 1:30 p.m., the “de Blasio for resident” account had yet to receive a single email in support of his presidential bid, according to Selvig.

“It seems like this country is full of people who either don’t know who Bill de Blasio is or wish they didn’t know who Bill de Blasio is,” Selvig said.

A de Blasio campaign spokeswoman did not respond to request for comment.
