I agree with Ralph on some issues and disagree with him on a lot of issues.
If the Democrats and Republicans would have ignored him, he probably would not have gotten much news coverage. Look at Badnarik, Peroutka, and Cobb.
We may have a Libertarian, Constitution, or Green Party President one day. It probably won't be Badnarik, Peroutka, or Cobb. But when it does happen, that person and the party will owe its gratitude to everyone in the past who helped build that party. Nader ran as an independent. No doubt he did help the Green Party a lot in 2000, but in 2004, he has little if anything to show for his work where as the other candidates at least helped a party grow.
I found this article while searching for some third party news.
http://illuminati-news.com/nader's-truce.htm It says if Nader were to use the coverage he was getting to help the other parties, they could begin to chip away at the R and D's.
