“the prisoner of his own impulse”

Inside Trump’s shutdown turnaround:

His poll numbers were plummeting. His FBI director was decrying the dysfunction. The nation’s air travel was in chaos. Federal workers were lining up at food banks. Economic growth was at risk of flatlining, and even some Republican senators were in open revolt.

So on Friday, the 35th day of a government shutdown that he said he was proud to instigate, President Trump finally folded. After vowing for weeks that he would keep the government closed unless he secured billions in funding for his promised border wall, Trump agreed to reopen it.

He got $0 instead.

Trump’s capitulation to Democrats marked a humiliating low point in a polarizing presidency and sparked an immediate backlash among some conservative allies, who cast him as a wimp.

Elected as a self-proclaimed master dealmaker and business wizard who would bend Washington to his will and stand firm on his campaign promises — chief among them the wall — Trump risks being exposed as ineffective.

“He was the prisoner of his own impulse and it turned into a catastrophe for him,” said David Axelrod, who was a White House adviser to President Barack Obama. “The House of Representatives has power and authority — and now a speaker who knows how to use it — so that has to become part of his calculation or he’ll get embarrassed again.”
