I'd laugh, but a potential consequence (for the third and perhaps most likely time) is a default on the US national debt, thanks to our bizarre practice of requiring a separate House vote to make the payments on debt we already spent, and speaking of it publicly in a manner that makes it sound analogous to raising a credit limit.

It's quite possible that the only reason the global economy did not collapse in 2011 or 2013 was that John Boehner was not Tea Party enough to let it happen. Now he's gone.
