Keep voting for them and keep getting the same results. The only change. . . peaceful change, anyway. . . is to stop voting for them.
I mean, what's next? The left proposes a top income tax rate of 90% and McCain and Co. offer up a "better" rate of 80%? Democrats propose a $25 minimum wage and the people we voted for compromise at $20? Democrats propose busing and shipping people from every country on the planet to get in here and immediately go on the dole, while republicans agree but just want to limit the number of cruise ships we pay for? You can't let people win because they are slightly less evil.
There are conservatives in China, Russia, and N. Korea, but "certain things" happen when they speak out. This will soon be happening here, too. Entertain yourself while you still can, although the country keeps sliding downward. There's only one thing left.
