Why do people think that Rep or Dems winning the house or senate will make any difference?

Let us stop kidding ourselves and face the fact here...We all bicker as to how Rep or Dem are screwing us..We say hey dems are worst the other side says no Republicans are worse..Seriously? Who cares about who wins next election . Fact is this, this country is going down the toilet and we are front roll sit?? You can have 15min of happiness because Dems or Repubs. are loosing next election...Fact is it doesnt change the outcome.. Einstein defined insanity as: doing same thing over and over again and expecting a different result.
