For a president that is unable to plan, unable to negotiate, unable to reach consensus, unable to govern, the shutdown is his crowning achievement. And his supporters love it too. Imagine it, a support group that doesn't believe in government, electing a president who is unable to govern. A shutdown is perfect for both Trump and his supporters because, in their minds, government workers are not necessary. TSA, who needs them? Government data, who needs it? Weather data? Why? Food inspections? Meh.
When asked if Trump can empathize with unpaid federal works, he shrugs and says yes. In his life, the president has never faced adversity, never wanted for his next meal, so the workers on furlough who are not working, or the workers who are working for zero paycheck... makes no difference to him... or his supporters... because Trump supporters want only what is best for themselves. Love they neighbor? Just a piece of fiction. Do unto others what you would have done to you? Feh, stupid babble.
Look at the timing of the shutdown. Just as the president is asked to work with divided government, he shuts the entire thing down. Can't manage it, shut it down. The president had 2 years of a republican controlled House and Senate, but could not get a deal done. But how could he get a deal done? The guy can not make a deal to save his life. So when faced with the idea that he would have to negotiate, he stops the entire process.
Imagine if your job functioned like the Trump administration? Imagine if everyone at your company was a Trump supporter?
