DES MOINES — Mayor de Blasio tried to display some presidential fortitude by traveling through near-blizzard conditions in Iowa — and wound up sleeping in a roadside motel after chowing down on a gas-station burrito for dinner.

Reporters from New York City wisely decided to wait out a snowstorm in Sioux City following an event at which de Blasio touted his progressive agenda to about two dozen residents on Saturday night.

But the mayor ignored the dangerous weather and insisted on heading south to Des Moines with his security detail.

Hizzoner made it less than halfway before calling it quits in Onawa, Iowa — estimated population 2,849 — to bed down in a Super 8 Motel, sources said.

And instead of enjoying some of the Hawkeye State’s award-winning barbecue or succulent steaks, he had to make do with a microwaved burrito.

De Blasio finally arrived in Des Moines around 9:30 a.m. Sunday, where he visited the Smokey Row Coffee Co. cafe and held a roundtable discussion with Mayor Frank Cownie, Councilman Chris Coleman and others.

He later had breakfast in a booth at the landmark Drake Diner, where former Gov. Tom Vilsack — who’d already eaten — sat with his hands folded across the table.

De Blasio is finishing up a two-day visit to Iowa, where caucus-goers cast the first votes for the nation’s presidential wannabes.

De Blasio has yet to declare if he’ll join the increasingly crowded Democratic field that’s vying to take on President Trump in 2020.
