On Wednesday, to the surprise of everyone, President Trump cut a deal with Democratic congressional leaders Sen. Charles E. Schumer (N.Y.) and Rep. Nancy Pelosi (Calif.) on the debt ceiling, affectionately calling them “Chuck and Nancy.”

But on Thursday morning, in an odd case of some pretty unfortunate timing, Trump's campaign launched an ad deriding Chuck and Nancy as “career politicians” standing in Trump's way. Here it is:

The ad begins by flashing pictures of Schumer and Pelosi as the narrator intones: “Career politicians and the media, trying to stop him” — referring to Trump.

The ad concludes by urging those apparently nefarious actors to “let President Trump do his job — and make America great again.”

Trump himself, apparently, has considerably less fight in him. By several accounts, he took the first deal Democrats put on the table for a short-term extension of the debt ceiling. Here's how The Post's team recounted it:

At the White House, Republican leaders pushed for an 18-month debt-limit hike, then floated doing a six-month extension, according to two aides briefed on the meeting. But Pelosi and Schumer dismissed the six-month proposal, and Trump then agreed to the three-month hike that Democrats put on the table.

Schumer and Pelosi are certainly standing in Trump's way on other issues, it bears noting. But apparently Trump's unpredictability is giving even his own ad-makers a tough time. With Trump, every alliance and adversarial relationship is subject to change at a moment's notice.
