If your answer to losing is to declare yourself “done with politics,” then you don’t really have the stamina necessary to be a participating citizen. Which is just as well. Democracy requires the continuing participation of the losers, and if you do not have the stones to play the game again the next time then you are part of the problem, not part of the solution.
Giving up just reinforces the loss. When handed a bad hand, like we’ve been handed this year with McCain walking away with the nomination, a redoubling of efforts makes more sense than quitting.
