The Wall
Matt Yglesias, writing for Vox, has an idea why the government shutdown is not likely to get resolved anytime soon.
You should read the whole thing, but basically his thesis is everyone on both sides of the aisle (except Trump) thinks the wall idea is stupid and expensive. Democrats might give Trump funding for something in return worth five billion dollars. DREAMers citizenship might be worth it. However, Republicans don’t want to give up something like that for something they don’t believe in. Hence, nothing getting done.
This might be the straw that breaks the camel’s back regarding Republicans supporting Trump. I mean, Democrats shouldn’t budge one inch unless they get something of equal value in return. Republicans should abandon the sinking ship that is the Trump Administration and start thinking about how they can cut him loose and not get cremated in 2020.
