Washington was consumed Wednesday with a fight between President Trump and Steve Bannon, his erstwhile Svengali. Their exchanges via book excerpts and press releases entertained used up all the Beltway bandwidth. Even the campaign of the Senate’s customarily laconic majority leader, Mitch McConnell, R-Ky., tweeted out a photo of him laughing at the fracas.

But the Senate is back in session, and McConnell has something of substance to take care of. Specifically, Obamacare still stands, and the nation is still on the road to a single-payer system, which it should avoid.
