Here's the question. Nader is not running under any party banner so he won't get on the ballot that way, and he's said he will not use his own money to get on the ballot. He doesn't seem to have any support from the big-money celebrities who backed him last time -- quite the contrary. I've seen estimates that getting successful ballot access petitions completed and filed costs about $1/signature (this isn't paying people to sign, it's the cost of signature gatherers and administration to review the petitions and get them filed). Spread over the country, you're talking about millions of dollars to get on the ballot, even in key big states.
So who is going to pay for Ralph's ballot petitions? Follow the money here, kossians. Support your state Democratic party in requiring letter-of-the-law, timely public disclosure of where Ralph is getting his money. Just like Reverend Al is bankrolled by Republicans (who clearly didn't get what they thought they were paying for), just like Republicans have supported Greens to run in places like New Mexico, expect some corporate thug/Bush Pioneer/Ranger to be bankrolling Ralph.
The point of this diary is not to engage in a debate with dyed-in-the-wool Ralphians. At this point, no one is going to persuade anyone else on the merits or demerits of his running. The point is, let's look at the reality of who really wants him to run, and keep a close watch on who's supporting him under the table.
Leading Democrats should call on Nader to screen his contributions and pledge to reject any money from anyone who has contributed to Bush. That's all on record and easily-identified information.
