To think, just 72 hours ago it looked like this morning’s Sunday shows would be wall-to-wall retrospectives of Trump’s first year as president on the anniversary of his inauguration.

Stuff happens, though, so instead it’ll be wall-to-wall shutdown fee-vah as Republicans and Democrats scramble to blame the other party for the mess. The White House’s chief advocate this morning is OMB chief Mick Mulvaney, a shrewd choice. Mulvaney palpably enjoys political combat and is a forceful advocate for his side; he’s a natural to take the lead on the GOP’s #SchumerShutdown message. He’s the lead guest on “Face the Nation,” “State of the Union,” and “Fox News Sunday.” Expect him to be pressed on whether it’s true that Chuck Schumer really dangled funding for the wall as a pot sweetener in his pre-shutdown meeting with Trump on Friday.

Democrats, of course, will counter with a #TrumpShutdown or #Sh*tholeShutdown narrative. Schumer himself isn’t booked — yet — as I write this on Saturday. Right now the biggest Democratic names scheduled are Dianne Feinstein on “Face the Nation” and Sunday-show mainstay Bernie Sanders on “State of the Union.” But expect that to change with plenty of hastily arranged bookings by congressional leaders to plead their case to the viewing public. McConnell, Ryan, Pelosi, and especially Schumer, as the lead Democratic negotiator, are all likely this morning.

If you’re not in the mood for shutdown politics … you’re out of luck, sorry. It’s Shutdown Sunday! The full line-up is at the AP.
