The GOP threat to close the government on 10/1 if the 2014 budget contains any funding for Obamacare is laughable. Obama will veto any bill that defunds his signature achievement and a veto override is impossible as it requires a two-thirds majority in both chambers. Moreover, dare I remind anyone, the most recent attempt to close the government on 1/1/13 resulted in the GOP voting for a humiliating tax increase.
