This race is driving the Democratic Party bigwigs bonkers. The only Democrat who might have had the clout to step in and stop the carnage happens to be married to one of the candidates, and his stature is diminishing by the day, anyway.
Behind it all runs a leitmotif of Machiavellian psychobabble:
1: "She knows she'll lose, and she wants to make sure to destroy Obama on the way out. That way, McCain wins the general, and she comes back in four years as St. Hillary, the patron saint of I Told You So."
2: "Spite. If she's going to lose, she wants to take him and the party down with her as punishment for not picking her in the first place. How dare the vermin stand in her way?"
3: "She'll do anything to win, and worry about dealing with the hurt feelings later. The Clintons defined winning dirty. Her base, the shoulder-pad feminists of a certain age, see this as simply being tough in a tough world."
4: "The longer she manages to stay in, the higher the price she can exact for agreeing to get out. Governor of New York? Senate Majority Leader? Chief Justice Clinton?"
I believe all of it.
