He’s fighting for your rights! From the couch!

Posters mocking Mayor Bill de Blasio’s quixotic presidential bid went up around City Hall Thursday — inviting people to attend his “debate watch, watch party” at Gracie Mansion.

“Come watch ‘presidential candidate’ Bill de Blasio watch the Democratic presidential debate from the couch,” mocked the poster shared to Reddit.

“He didn’t qualify, but you can hear how he would have responded to the questions as he yells at his television,” it continued, accompanied by a photo of Hizzoner reclining in front of a TV set.

Hizzoner was indeed tuned in, firing off tweets from the couch at Gracie Mansion touting his record on pre-K and 3-K, a $15-hour minimum wage and his Green New Deal — borrowed from upstart Bronx Rep. Alexandria Ocasio-Cortez.

“You won’t see me on stage tonight. But I’m joining you to watch the #DemDebate live — and I’ll hold to task every single one of the candidates on stage,” de Blasio tweeted as the debates kicked off at 8 p.m.

Pundits seized on the tweet — telling the mayor to get back to his job.

“We won’t see you at the office tomorrow either. Maybe the gym. But not the office,” wrote one unimpressed New Yorker.

“I’d rather you do your current job as mayor,” offered another voter.

The Post last week revealed Hizzoner spent a mere seven hours at work in May, taking part in two meetings, four events and five phone calls.

De Blasio did not make the cutoff for the Thursday evening debate in Houston after he failed to get at least 2% in four polls or 130,000 donors.
