Because it’s Hillary Clinton’s fault. It’s Hillary Clinton making Americans ill with anxiety. For example, she has continued to say that McCain is better than Obama; in fact, she’s gotten a little more straightforward about it, if anything. I expect her one day to argue that she should be the nominee because she has given McCain so much ammo to use against Obama.
BTW I agree with P. M. Carpenter (http://www.buzzflash.com/articles/carpenter/004) and thus disagree with Big Tent at TalkLeft, who thinks that Obama not beating Clinton in the big states (except Illinois and Georgia) means Obama would be weak in those states versus McCain. Big Tent is channeling Phil ‘No Room in the Majors for a .500 Pitcher’ Rizutto, or maybe he is in psychic link with Jack Welch, who thinks you can improve the quality of a workforce by repeatedly ranking your workers and firing the lowest ranked. (Or has Welch done us the favor yet of leaving this world?... Nope, apparently not.)
