For all the mockery of Kamala Harris’ call for a “No Bad Idea Brainstorm,” the ex-veep did the public a service in flagging how determined the Democratic elite remains to “blame the umpire” for their losing streak.

Their party keeps pushing terrible ideas and awful candidates, but changing any of that would be painful and internally divisive.

So the faithful instead fantasize about changing the rules: Lose the Electoral College; end the filibuster; pack the Supreme Court; admit new states guaranteed to elect Democrats to the Senate — every bit of it stuff not just Harris is now pushing, but also once-centrist strategists like James Carville.

Sure, the instinct to claim the fix was in runs all across the spectrum: Just look at President Donald Trump after the 2020 vote.

And we expect plenty of Dems know the real roots of their troubles; thing is, most don’t say it out loud: Witness the hate for still-really-lefty Sen. John Fetterman.

Even when the umps are unfair, the smart teams figure out how to improve enough to win anyway.

Just whining about the game being “fixed” is how losers remain losers; credit Kamala with tacitly admitting that by owning up to the “Bad Ideas” label.
