I read the headline, "Casey calls House GOP '3rd graders' in shutdown threat," and thought "He is being too kind -- 1st graders is more like it."
The "tea party" members of the GOP are acting like children who throw tantrums when they don't win, especially when they have to play by rules that don't favor them.
The Affordable Care Act, aka "Obamacare" has only partially taken effect, and people who haven't fallen prey to the disinformation campaign do not "hate it."
It was deemed Constitutional by the Supreme Court. Risking the credit rating of the nation over it is insane, and will cost far more money than might be saved by "de-funding Obamacare." I hope Congressional salaries are the first thing that do not get paid when the government shuts down.
