According to Robert Novak:
Supporters of Sen. Hillary Rodham Clinton (D-N.Y.) are truly worried about Sen. Barack Obama (D-Ill.). He is showing signs of being a genuine phenomenon who could sweep through the primaries and take the Democratic nomination. The question for Clinton strategists: Should they attack Obama?
Of course I've been telling everyone this for months.
And as to Novak's "question" as to whether they should attack Obama or not - the answer is, "they already have!"
