I can't see how it matters one way or the other. Even if some new blood gets in the White House, it won't happen, but even if it does the federal govt system is broke and utterly corrupt. Lobbiests and special intrest groups write our laws and legally bribe, coerce and pay off our elected officials. If you're not corrupt when you arrive in Washington, you soon will be. Corruption is the staus quo. If a 3rd party gains control of the White House the senate and house, assuming one or both are controlled by the Dems and/or the Repubs, will put up partisan roadblocks all along the way to prevent the 3rd party controlled White House from doing anything. Dems and Repubs both have long lost sight of bettering this country and helping the people and working together for a common good. Now their only goal is to win votes and gain control.
I didn't used to be so cynical. The last 8-10 years have soured me on national level politics. If it were up to me I'd sweep Washington DC right into the Atlantic Ocean and start all over. Move the Capital to the middle of the country somewhere, a president could only serve one six year term, congressman would have term limits as well, every man and woman would serve a stint in the military as soon as they turned 18, and if a lobbiest was caught within 100 miles of an elected official he or she'd be immediately shot.
Ahhhh, these little rants of mine are very cathartic
