I think Hillary is showing really bad judgment by prolonging the contest and dividing her party. She also showed poor judgment when she voted for the Iraq war, but at least she has the excuse of having received faulty intelligence from the administration (although I think she voted for the war b/c that was the way the wind was blowing after 9/11 and she didn’t want to alienate would-be voters).
But there’s no excuse now, she has all the facts. If she shows this bad judgment as a candidate, what can we expect of her if she ever becomes president? If, say, Obama loses in November, she could be a natural candidate in 2012. But her actions are not only hurting her party, they are hurting her political career as well.
