Democrats control the Presidency, Senate and House of Representatives because they were elected. Four out of five voters are now dissatisfied with the way things are going. How many of the 79% do you suppose will vote Democratic on November 2?
Another way of phrasing that question is, how many of the 79% are insane? To have voted Democrats into office, to now be dissatisfied with the way things are going, and to reelect Democrats is what Einstein called insane behavior. It is doing the same thing over and over again and expecting different results.
