Fighting the Persian invasion into Greece was a "lost cause."
Then along came Leonidas at Thermopylae.
Revolting against the tyrannical George III of Britain was a "lost cause."
Then along came Washington (with French military support) at Yorktown.
Now, as to the present fight for limited and Constitutional government, you may be right. Closing the Pandora's box of Big Government may well indeed be a "lost cause." And there may very well be no Washington or Leonidas or even French military success today, but it is far preferable to go down fighting for what is right and proper and good than to admit defeat and surrender like a coward and a slave and a traitor.
Going down fighting is one thing. But defeat is defeat. When the games over, and the scoreboard says you lost, you can run another play if it makes you feel better, but the game's already over. The results are in. The standings have been updated. It's over.
So what to do, right? All I'm saying is the problem is much worse than it even looks. It isn't just RINOs. It isn't just the GOP. The conservative movement itself is apparantly incapable of staying within constitutional limits. I keep harping on tort reform, and "letting states sell insurance across state lines", because they are topics de jour. Conservatives from top to bottom support these measures. No one stops to question whether it's legitimate federal power.
So, that means it's the DEMs, RINOs, The GOP, conservative talk radio, Club for Growth, and anyone else you can think of that are AGAINST limited gubmint. They only like it when it suits them. So that's the situation.
I personally think America should be busted up. I hope one day it gets so bad that states start to break away, and modern Western wimps don't have the balls to do anything about it. Then at least people can start from scratch. But the American experiment is a failure. It's still a nice place to live, all things considered, but miles and miles removed from what it was supposed to be.
