Who are the 11%?

Congressional approval ratings at an all-time low.  Surprising?  Not really.  This is the most dysfunctional Congress that I have ever seen, without any doubt.  No matter your party preference, nobody should be satisfied with a Congress that is so deeply entrenched in partisan gridlock that they can't get anything done.  What would happen if there was a real, sudden national crisis? My fear is that they couldn't get together to respond in a timely manner.
