One thing a nation watching nervously as the coronavirus spreads doesn’t need is the usual partisan Washington bickering.

President Trump aimed for that in his Oval Office remarks Wednesday night, avoiding slaps at Democrats’ proposals even as he announced an outside-the-box ban on travel from Europe, where COVID-19 is booming — Germany expects a 70 percent infection rate.

Some will condemn that out of and , even as others ask why the ban’s not global. Either way, he’s setting normal politics aside.

Not Democrats. Just look at their reaction to one of his earlier suggestions to bolster workers likely to suffer as industries slow: a temporary payroll-tax cut.

Dems loved that idea when President Barack Obama proposed it in 2010 in his second stimulus package. Speaker Nancy Pelosi called it a “victory for all Americans,” trumpeting how much it would put back into people’s pockets. But Trump makes the same request, and she calls it “tax cuts for major corporations.”

Word is that Pelosi and Sen. Chuck Schumer, as they meet with Treasury Secretary Steve Mnuchin to discuss economic-stimulus plans, have drawn up an all-spending legislative package, with zero input from Republicans. Plainly, the idea is to get the White House to bully the Senate GOP majority into going along.

Democrats and Republicans ought to be able to work out some no-brainers themselves, e.g. ensuring that everyone can afford coronavirus testing. Team Trump got insurers to waive co-pays and extend coverage. Some program to cover all uninsured (including illegal immigrants — this is about stopping an epidemic) is a must, as is bolstering a health-care system facing an onrush of patients.

And the economy, and the folks who work in it, can surely use some help. Mnuchin set out some decent ideas on Wednesday. Tax extensions and deferrals, for example: “We think we can provide over $200 billion of liquidity into the economy by delaying certain tax payments.”

Compromise is possible, even now. Pelosi and Mnuchin managed to forge a budget agreement late last year, raising the debt ceiling and preventing a federal shutdown. Let’s hope they can repeat it.

Congress should show it’s on the job — canceling next week’s planned recess if necessary to get any key bills passed. Build Americans’ confidence, people.
