Progressives got squelched at the fall meeting of the Democratic State Committee this week. But you can bet they’re singing “Tomorrow belongs to me.”

Floor motions were still pending when Gov. Cuomo’s cronies ended the meeting without a vote to gavel out. Among the resolutions stifled was one seeking accountability for the committee mailer that painted Cynthia Nixon as an anti-Semite. Another called for an end to cross-party “fusion” endorsements.

The dust-up foreshadows the coming larger clash between the party’s status-quo center and the rising progressive wing.

The old guard also held on last week in Brooklyn, using obscure rules and scores of proxy cards to retain control of the county party committee against younger insurgents. Similar tremors hit the usually staid county committee meetings in The Bronx and Queens last month.

What played out at Monday’s meeting is similar to what’s happening in other parts of the state as energized young Democrats are challenging a rigged insiders’ game.

We’re not remotely eager to see the Left gain the upper hand in the party, especially when it stands a good chance of winning control of the state Senate, leaving Democrats unchecked in Albany.

But in the long run, it’s very hard to beat passion and idealism, however misplaced, with procedural ploys and dirty tricks.

Cuomo likes to portray himself as the sober centrist holding against his party’s extremes — even if, as his campaign against Nixon showed, he’s perfectly willing to shift as far left as needed to keep power.

His problem — and the peril for all New York — is that progressives won’t settle for anything but total victory.
