Gee Whiz, give it a rest already. Are you still working the first job you ever had? Have you always worked at each job exactly as long as everyone else thought you should? What if you made a commitment to doing what was best for the company, and it turns out at a particular moment, you quitting was the best thing for the company? Is that still quitting? Or what if you're a commander with troops who trust your judgment, and you decide to strategically withdraw from one battle so you can regroup for a more important one? Are you still a quitter then? Even George Washington was a quitter by those standards.
Look, if we don't keep and nurture our own best talent (Palin, DeMint, etc.), who will we have left? Brainless people who don’t know enough to quit a dead end when they ought to, that's who. We can't afford to be leaderless, least of all over non-issues. You give up your vote for DeMint if you must, but I promise you this; I will see that vote and raise you two more (No, not cheaters votes, persuaders votes, the good kind), just to make the point. If an army is going to win, it needs troops and it needs commanders. If we "shoot" all our own commanders, and especially those with exceptional strategic skills, how does that help us?
And this is different than all the people around here that jumped on Palin for doing the same thing?
