Republicans have a lot to learn about being a majority and crushing their opposition without mercy. The Right could have torn the Left apart, but the Right hadn't the will nor the presence of leaders with a killer instinct.
Too damned bad.
As for who's to blame.....we all have mirrors, don't we.
What needs to happen starting tomorrow, is the Republican party needs to take a good hard look at itself and figure out what their base wants out of it.
