Dan Gillmor: "People say there are two Americas. I think there are at least three.

One is Bush's America: an amalgam of the extreme Christian "conservatives," corporate interests and the builders of the burgeoning national-security state.

Another is the Democratic "left": wedded to the old, discredited politics in a time that demands creative thinking.

I suspect there's a third America: members of an increasingly radical middle that will become more obvious in the next few years, tolerant of those who are different and aware that the big problems of our times are being ignored -- or made worse -- by those in power today.

That third America needs a candidate. Or, maybe, a new party."
