A showdown this week pits House progressives, who want Speaker Nancy Pelosi to stick to her guns and keep the $1 trillion bipartisan infrastructure bill off the floor until Team Biden’s $3.5 trillion “human infrastructure” bill gets passed, against moderates who say they won’t support the massive measure unless the smaller bill becomes law first.

Let’s hope the moderates stick to their principles.

They’re right to stand up to Pelosi. Not only is a progressive, partisan spending spree bad for a recovering economy; voting for it, whenever it comes up, means political suicide in swing districts come next year’s midterms.

Pelosi on Monday put the wheels in motion for votes on both bills, but still insists on her way or the highway.

But she doesn’t have the numbers for it if even half the nine moderates stand their ground, since Dems have a tiny 220-212 majority.

“With the livelihoods of hardworking American families at stake, we simply can’t afford months of unnecessary delays and risk squandering this one-in-a-century, bipartisan infrastructure package,” the moderates, led by Rep. Josh Gottheimer (D-NJ), wrote Pelosi.

Better still was Rep. Henry Cueller (D-Texas): “No progressive is going to cram something down my throat.”

Meanwhile, progressives led by Rep. Alexandria Ocasio-Cortez (D-Bx/Queens) vow to vote down the infrastructure bill if they don’t get their wish-list legislation first. Hey, neither bill is better than this $3.5 trillion monstrosity.

Another reason for moderates to be wary: President Joe Biden’s plummeting approval ratings, down 10 points in a month — and not just because of his Afghanistan debacle. The public is souring on a prez whose words defy reality across the board, from the economy to border security. His rosy predictions of prosperity from his over-the-top spending plan deserve no more trust than his claims about having planned for all Afghan contingencies.

Americans struggling to get back to normalcy can’t afford the big-government giveaways in the $3.5 trillion bill — and its tax hikes will only slam an economy still stuck in its own struggles.

Sensible Dems must stand up against far-left dreams that mean big trouble for working people.
