Rich Lowry of National Review Online analyzes congressional Democrats’ loss in the government shutdown showdown.

Chuck Schumer started a government shutdown he couldn’t finish.

The New York Democrat, among the shrewdest operators in national politics, stumbled badly because he succumbed to the siren song of the anti-Trump resistance. He believed that any charge could be made to stick to President Donald Trump, no matter how implausible, and chose the dictates of an inflamed Democratic base over common sense.

His embarrassing climbdown after a short, mostly weekend shutdown shows the limits of the resistance. Yes, an anti-Trump midterm wave appears to be building, and Democratic activists — marching in the streets by the tens of thousands and badgering Republicans at town-hall meetings — are energized. But this doesn’t mean that Democrats can act with impunity so long as they are fighting under an anti-Trump banner.

Schumer sought to attach an extraneous matter, an amnesty for so-called Dreamers, on a must-pass government-funding bill and, when Democrats inevitably didn’t get what they wanted, blame President Trump for the ensuing government shutdown. This effort depended on gravity-defying spin that proved sustainable for less than three days.
