Dems have really put themselves in a tough spot with this shutdown. The overwhelming majority in the country do not want to see a government shutdown for resolving DACA....
... but the Dem base has been so radicalized that inevitable Dem backtracking will result in tantrums among the base, which is pretty weak in terms of anything binding it together beyond "resist".....
... if the roles were magically switched and I were an immoral Dem I would love to see the "opposition" squirm with a shutdown that went on for a week or two, but that would be if it were purely about politics, and not other things, incl. military....
