Barack Obama is winning, so why does it look like Hillary Clinton is having all the fun?

Senator Obama has been thrown completely off his game by a combination of political attacks (some fair, some foul), a toxic eruption (the volcanic Jeremiah Wright was a gift from the gods to the Clintons and the G.O.P.), and some pretty serious self-inflicted wounds.

You can almost feel the air seeping out of the Obama phenomenon. The candidate and his aides are brainstorming ways to counter the Clinton death-ray machine and regain the momentum. They need to generate some new excitement and enthusiasm, and they need to do it soon.

Despite all the new voters who have been brought into the process, Democrats are filled with anxiety about their prospects in November. A nervous operative told me on Friday: “If we lose this election, it would be like Johnson losing to Goldwater.”

One of the problems is that anger is growing like a cancer among Democrats. The Clintons have more than lived up to their polarizing reputations, slicing and dicing the electorate and then gleefully exploiting the myriad divisions.
