There will never be a one party rule. The country is simply too diverse.
The greatest diversity is not sex, skin color, religion, ethnicity or orientation. It's diversity of thought. And that, my friend, you are crushing. Lieberman was drummed out of the party for disagreeing on one issue. That ... is what is winning ...
Remind me. What issue was that?
Sure, I'll educate a liberal. When the left were all running around against Iraq, Lieberman still supported it. The National Democrats all came to Connecticut and successfully defeated him in the primary with a vacuous liberal moron. Lieberman ran as an independent and won.
As an "independent" he still caucused with Democrats. The Senate was divided and had Republicans pulled him over, which they tried, they'd have run the Senate. Even after trying to oust him over one issue, he kept them in power. Then once they had a larger majority the Democrats finally punished him by kicking him off his best committee jobs.
These would be the same Democrats who once their messiah took over decided that it was "unpatriotic" to question a President on anything when troops are in combat. Now they're totally good with warrantless spying on Americans. And the insist they are consistent. What a bunch of mindless sheep you are.
