The problem with political parties... OKAY there are far too many problems, so the problem with them RIGHT NOW is that they existed as groups which various people in the nation COULD fit into depending on issues at the time and the basic properties for EACH party - right now being the Republicans and Democrats - is that they NO LONGER represent what they did originally, nor the people they were meant to, nor are they even opposites anymore. They're just babies throwing temper tantrums.
Democrats were meant to be mid-left wing so that they could represent the left wing as a whole. Now they are low-left wing mid-right wing with no experts for either side. Republicans were supposed to be mid-right wing, for the same reasons, but now they're far-right wing and low-left wing.
In other words, we don't even have any proper left-wing people in office, and the right-wing people in office have too much stuck up their behinds to help each other fix the nation.
The tea party is...well, far right and far left, it just depends on what parts of those you choose from. They're max radical on both wings, which causes the wings to rip off of the body, slowing causing the nation to bleed to death.
