Mayor Bill de Blasio, who’s repeatedly ditched the city since launching his quixotic presidential run, may hate hanging around New Yorkers.

But some of them are so mad at him, they’re willing to track the derelict mayor all the way to Iowa.

At a breakfast meet-and-greet in tiny Hiawatha, two New York City high school students peppered Hizzoner with questions about police in public schools. They were among roughly 40 locals at the Karma Coffee Cafe, NY1’s Gloria Pazmino reported.

Meanwhile, low-polling presidential rival Rep. Tulsi Gabbard (D-Hawaii) drew 400 to a speech at a Downtown event space — 10 times bigger than de Blasio’s crowd.

Gabbard carefully avoided trashing de Blasio, flip-flopping front-runner Joe Biden, Sen. Bernie Sanders or anyone else in the crowded Democratic presidential primary.

“I’m not running against him, I’m not running against anyone else,” she said.
