President Trump said Wednesday that he sees “no political appetite” for restrictions on the sale of assault weapons. Guess he’s not looking in the right places.

Because last weekend’s mass shootings were the last straw for much of America: Voters are now hungry — desperate, actually — for meaningful action, like a ban on the high-powered weapons so often used in these mindless massacres.

Fact is, we’re starving for such limits.

Trump surely senses the nation’s desperation. It’s part of why he traveled Wednesday to Dayton and El Paso and listened respectfully to demands for him to “do something.”

It’s also why Sen. Sherrod Brown (D-Ohio), a fierce Trump critic, broke with the Democrats boycotting the president and met with Trump in Dayton — taking the chance to plead for action.

And shame on all the Dems ignoring the majority of Americans who don’t want partisanship to derail efforts to end gun madness.

Trump, meanwhile, has at least recognized that “there is a great appetite” for tougher background-check laws, such as the bill the House passed in February. He’s now predicting a deal on that, perhaps including a national red-flag law (to allow court orders that bar dangerous individuals from possessing firearms). It’s a shift from his threat to veto background-check legislation.

That he and increasing numbers of Republicans in Congress are now open to new measures is evidence that some of Washington is hearing the calls for action.

Trump likely thinks too many GOPers will draw the line at an assault-weapons ban. But what’s to stop him from giving them an extra push?

Make no mistake: The background checks, red-flag laws and other measures Trump has touted (like better attention to those with mental illnesses) are useful steps. But the problem has now reached grave proportions; it requires a bold, comprehensive solution — one that includes an assault-weapons ban.

A strong drive by Trump could make it happen. And the result would be more than “just” fewer shootings: A major rebuke to the extreme partisanship that’s frustrated so much of his agenda would remake the political environment all the way through the 2020 election.
