President Trump has lobbed some whoppers during his 19 months in office: Democrats are organizing a caravan of Honduran migrants hoping to enter the United States illegally. US Steel is building six new steel mills. His poll numbers are the highest ever for a Republican president.

If none of those is your favorite, there are nearly 5,000 other lies and misstatements Trump has uttered since becoming president. And then there’s a new one.

With the midterm elections two weeks away, Trump now says the White House is planning a “major tax cut for middle-income people” that he’ll reveal right before the election. Trump told reporters Oct. 22 that he’ll produce a “resolution” calling for a 10% tax cut for middle-income earners.

For those wondering if it really works this way—no, the president can’t roll out a tax cut on short notice like this. There’s no procedure for cutting taxes via presidential resolution. Only Congress can initiate a tax cut (or hike) and Congress is out of session until after the midterms. So it’s impossible for Trump to cut taxes in time to buy your vote, as he seems to wish he could.

Trump mentioned this new tax cut idea in a session with reporters after a Nevada rally on Oct. 20. One can only imagine the urgent questions among Trump’s aides: Does he really mean it? Are we now going to make it look like there’s an actual plan for this? Or will this be a one-time, fire-and-forget Trumpism?

Looks like it’s a keeper. On Sunday, Treasury Secretary Steven Mnuchin tried to make it sound like there’s a thorough plan in the works, telling the New York Times, “this is specifically focused on the middle class and not beyond that.” But he didn’t have details on what tax brackets might quality for a reduction, or anything else. But don’t worry, a crack team of panderers is working on it.

Key Congressional Republicans, such as House Speaker Paul Ryan and House Ways and Means Committee Chairman Kevin Brady, apparently knew nothing about the express tax cut Trump had in mind–even though all tax legislation must originate in the House. But now, they say, oh, yeah, sure, Trump can outline a tax plan Congress can vote on later. So now it seems likely Trump and perhaps some other Republicans will make this part of their closing argument as voters decide whom to vote for.

If this all seems redundant, here’s why. Last year Trump signed a large, $1.5 trillion tax cut, with zero Democratic support, that was supposed to grease the midterm elections as voters everywhere thanked Republicans for all the extra money. Except many voters don’t feel they got any tax cut at all. Instead, they think the bulk of the tax cuts went to businesses and the wealthy, with crumbs left for middle-income families.
