re: How is it possible both sides of the aisle- their supporters believe

Perhaps the sad reality lies in the fact that both parties have betrayed the American people.
There is no way that approximately 537
Senators and congress people can legislate fairly for the 340,000,000 that occupy our land. These people care only for power to perpetuate the goals of the elitists who manipulate the common folk like puppets.
The great majority on both sides of the political spectrum are a decent, moral lot wishing freedom to pursue their dreams. The day may have arrived where the battle to exist depends upon the elimination of the politicos in D.C. who have abandoned us to further their agenda.
I shudder to think what havoc the aftermath of such a conflagration will spell for the remnants of the nation.
