Feingold: Too independent for the Dems?

The New Republic has a long, interesting profile on Sen. Russ Feingold.

Once you get past the obligatory question of "Is Feingold the new Howard Dean?" (no, he's not), it gets down to the real question: Is Feingold just to independent (some say quirky; he says principled) to keep the hard core Democrats happy? Could they bring themselves to vote for someone who doesn't toe the party line -- who even voted to confirm John Roberts?
