House Democrats aren’t even trying to build an impeachment case that has a chance of persuading the Senate to remove President Trump, which makes the whole exercise an elaborate waste of time. But maybe that’s the point.

Speaker Nancy Pelosi is plainly uninterested in actually getting anything done. Dems keep passing bills that have no chance in the Senate, either — while stalling on legislation that could actually make a difference.

No. 1 on that front is the US-Mexico-Canada trade deal, a k a USMCA. Pelosi’s members from swing districts are desperate to pass it — they won office promising to get things done, not to bog down in #Resistance. And trade fears are the main worry when it comes to keeping the economy growing; USMCA passage would surely help ease those worries, and so boost growth.

Oh, the speaker keeps saying the House is on track to OK the agreement. At the end of October, she said that no updates are a good indicator of talks moving forward. But weeks later, it’s still on hold.

Problem is, it would be a clear win for Trump, and so infuriate the Democratic base. So the speaker keeps making new demands, nominally to protect US labor unions but mainly just to gum up the works. Other bipartisan bills, like ones to keep prescription-drug prices under control, are similarly bottled up.

At best, the House will manage to pass whatever compromise bills are needed to keep the government funded through the end of the year — plus, yes, passing whatever articles of impeachment Jerry Nadler’s Judiciary Committee comes up with.

This isn’t remotely what the public wants. A recent CNN poll, for example, found that 46 percent of voters see the impeachment inquiry as extremely or very important. But that puts it far behind major issues like the economy, which hit 83 percent, and health care, 80 percent.

The work Americans want Congress doing just doesn’t matter as much to the speaker: She has politics to play.
