The two parties work surprisingly well together on issues that don't divide the citizens into competing factions. How do you think the NSA gets away with all the spying they do?
Example from my state of Illinois, Democrats control the state with a supermajority. We have an out-of-control pension system that everyone agrees with is a massive problem on our state's ability to pay its bills (look up stats on how far delayed hospitals are compensated from medicare/medicaid services), so much so that their is a current legal fight over whether the Democratic governor can legally reject legislature salaries until they do something, anything on the pension system. But they don't do anything because pension reform does not divide the public enough to motivate action from citizens.
You are living the political hackery. I'm at least making an attempt to remove myself from it all. You just conveniently translate it into "your beliefs suck, that's why you don't want to fight."
There is a group of people who believe Democrats and Democratic voters are against them with bullshit policies and greedy attitudes, and will only ever vote Republican.

Have fun drinking your kool-aid.
