Former NY Mayor Ed Koch has died of heart failure at 88.

Former Mayor Ed Koch, the combative, acid-tongued politician who rescued the city from near-financial ruin during a three-term City Hall run in which he embodied New York chutzpah for the rest of the world, died Friday. He was 88.

Koch died at 2 a.m., spokesman George Arzt said. The funeral will be Monday at Temple Emanu-El in Manhattan.

After leaving City Hall in January 1990, Koch battled assorted health problems and heart disease.

The larger-than-life Koch, who breezed through the streets of New York flashing his signature thumbs-up sign, won a national reputation with his feisty style. “How’m I doing?” was his trademark question to constituents, although the answer mattered little to Koch. The mayor always thought he was doing wonderfully.

Bald and bombastic, paunchy and pretentious, the city’s 105th mayor was quick with a friendly quip and equally fast with a cutting remark for his political enemies.

“You punch me, I punch back,” Koch once memorably observed. “I do not believe it’s good for one’s self-respect to be a punching bag.”

When President George W. Bush ran for re-election in 2004, Koch, a Democrat, crossed party lines to support him and spoke at the GOP convention. He also endorsed Mayor Michael Bloomberg’s re-election efforts at a time when Bloomberg was a Republican. Koch described himself as “a liberal with sanity.”

“He was fiercely proud of his Jewish faith. He fiercely defended the City of New York, and he fiercely loved its people. Above all, he loved his country, the United States of America, in whose armed forces he served in World War II.”

With him goes one of the last decent Democrats. May he rest in peace.
