If you're going to play, play nice

I agree with what Nicholas Kristoff says in his latest op-ed:

If Mrs. Clinton can run a high-minded, civil campaign and rein in her proxies, then she has every right to continue through the next few primaries, and the Democrats might even benefit from the bolstered attention and turnout. But if the brawl continues, then she and her husband may be remembered by many people who long admired them as having the same effect on Mr. Obama this November that Ralph Nader had on Al Gore in 2000.

It's not so much that she's staying in the race even though she doesn't have a chance of winning. It's that she's tearing apart her fellow Democrat--and her party along with him.
