One of the reasons that Obama has done so well is that Hillary has never really brought out the big guns against him, something that the McCain campaigns and the 527s will have no compunction about doing in the fall. His campaign (at least up to the point of the Reverend Wright controversy) was a hothouse plant, and it's likely to wilt when put out in the wild after the convention.
And why didn't Hillary hit him where it really hurts (as opposed to idiotic things like kindergarten essays)? Because those big guns are likely to backfire on her. Here's an example:
In her campaign for the Democratic Party's presidential nomination, Clinton has said little about her experiences in the tumultuous late 1960s and early 1970s, including her involvement with student protests and her brief internship at the law firm, Treuhaft, Walker and Burnstein. She has said she worked on a child custody case, although former partners recall her likely involvement in conscientious objector cases and a legal challenge to a university loyalty oath.
But her decision to target Obama's radical connections has spurred criticism from some former protest movement leaders who say she has opened her own associations to scrutiny.
"The very things she's accusing Barack of could be said of her with much greater evidence," said Tom Hayden, a leading anti-Vietnam War activist, author and self-described friend of the Clintons.
Next thing you know, she'll be accusing him of shady real-estate deals.
I heard something about Hillary! had to sit through a sermon at a church where the pastor was talking about the sin of adultery. She just blankly stared during the proselytism. You'd thought that pastor would have considered a rewrite knowing that Hillary! was going to be there.
