i thought this was a neat idea, from MoveOn:

"George W. Bush and some radical right-wing Republicans have stolen our country. We asked you last month if you were willing to fight to take it back. Hundreds of thousands of you answered with a resounding "Yes!" Now it's time to make some decisions about how to proceed.

In most presidential primary processes, pundits, pollsters and wealthy donors determine the outcome long before the actual primaries. By the time the rest of us cast our ballots, the nomination is typically a done deal. As we build our movement to defeat Bush, we could let that happen again. Or, we could engage in the primaries as a coordinated grassroots base. Should we?

We would like to start a candidate engagement process in which:

1) MoveOn members hear from candidates through email and our website.
2) We engage the campaigns on issues through an online interview.
3) MoveOn members vote online in a "MoveOn Primary."

If a candidate wins a majority in the primary, we endorse him or her.

Would you support this process? Tell us what you think"
