Hate to say it, but I think Mr Shepherd is on to something.  I didn't vote for Barack Obama in either 2008 or 2012, but once Obama was elected, I was ticked off by the attitudes of quite a few of the Republicans in both houses of Congress.  There were many, including Senator McConnell, whose main goal--in fact, main obsession--was making sure that Obama was a one term President.  Guys and ladies, didn't you have anything better to do than trying to prevent your President from getting re-elected?  And then these politicians spend lots of time and money trying to get re-elected themselves.  Maybe if they didn't spend so much time campaigning, they'd actually work with each other and start getting really important things done.
