Political parties

I believe that political parties are tearing our country to pieces.
The two main political factions in today's society are fighting such a fervent and angry tug-of-war with America, that it's probably just a matter of time before they tear the country apart, both holding so tight to what they think should happen.
In this "If I can't have it, no one can" attitude, both democrats and republicans have forgotten that each major campaign issue is an independent concern that needs to be worked out, and that the biggest concern of any group trying to run this country should be the best interests of its citizens, not the advancement of a political party.
I am truly disturbed that I have to vote in the upcoming presidential election for a candidate who only shares my opinion on a few major issues, because that's better than the candidate who only shares my opinion on one.
