He should drop out and be a patriot.
Look, people. Think.
You either honor the effort last year to stop McCains Amnesty or you do not.
Thats it. Full stop. You either honor that victory or you declare it moot and petulant.
You vote to award McCain the nomination, or you vote in the only way to prevent it.
This is not rocket science and you all know it. If you dont care about amnesty, McCain is your guy. If you do care, there is only one way to stop him. And you all know it.
Now you can wriggle around and talk about nuanced principles. Or you can look reality in the face and recognize the principle that trumps it all is victory against amnesty. Honor that victory, or spit on it. Choose.
