This should surprise exactly no one. Bush has nothing positive to run on, no accomplishments, so he’s going negative on an unprecedented scale. This is what the modern Republican party does, though. It’s what they’re good at. Expect a long campaign season full of lies and vicious attacks as Bush’s people try to convince people to hate Kerry enough to vote for a man whose incompetence has been unambiguously demonstrated.
And this isn’t a case of “oh, they all do that.” Read the article. Bush is going more negative, more often, and telling more lies. It’s not a tit-for-tat situation, as much as the right would like you to believe it is.
