Here are my basic problems with Nader and his supporters.
First of all, if he really wants to make a difference and be part of the political process, why doesn't he run for an office he can win? I bet you even as late as 2004 Oregon or Vermont would have sent him to the Senate, and many communities would send him to the House. His running this perennial hopeless campaign makes me question his real committment to social change and his motives in participating in the political process.
Secondly, his vendetta against the Democrats is immature and misplaced. Sure, the Clinton people should have returned his calls in 1992. But come on -- aren't there bigger issues at stake by now? During his years as a consumer advocate -- which no one can take away from him and for which he deserves the highest respect -- it was the Congessional Democrats that gave him a platform and credibility in Washington and helped turn his work into laws and regulations.
And finally, let's talk about the whole third-party concept. The problem with the phrase one hears someone groan every four years -- "the lesser of two evils" -- is that it implies that there was some halcyon time when democracy wasn't a choice between two corporate-backed weasels. The founding fathers understood this very well. They knew that the ballot box wasn't enough to ensure full participation, so they passed the Bill of Rights and its immortal First Amendment, guaranteeing the right to freedoms of speech, the press, assembly, petition for redress of grievances, etc. And, unlike voting, those rights were given to all citizens from the start, so it could be argued that they were considered more essential to democracy than voting. Historically, voting has always been more of a negative act than a positive one -- something Putin understands very well. The major reason to vote is to vote against tyranny (usually disguised as an ultra-nationalist friendly to business interests and the ethnic majority). The alternative is usually some less-than ideal guy who has his own issues, but at least he respects the democratic process, which, by the way, is supposed to be messy (tune into a session of British Parliament to see how it's supposed to work -- it ain't pretty.) The idea is to vote for a competent administrator who respects the Constitution and can negotiate its checks and balances to get things done in a way that offends the fewest people, not an ideologically pure knight on a shining horse. Voting for Nader is just as bad as voting for Buchanan -- or Bush. We don't need third parties, we need for the American people to take the system we have seriously and fully participate in it, and understand that it's our duty not to elect an ideal candidate, but to elect the least bad one and use our freedoms to lobby him/her on the issues important to you. It should have nothing to do with force of personality. TIme to grow up, people.
