I fully agree with that position. I do believe, however, that we can use their contradictions against them, as we always have in the class struggle. Today that means keeping Bush out of the White House. Bob is aware that a significant vote for Nader could put Bush in, but says it doesn't matter. He argues that Bush's sparse majority would give him pause and make him listen to the people.
Reality teaches the opposite.
The march toward the extreme right would begin anew. Strange as it seems, we all know he would. In such an atmosphere it will be feasible to start to build an authentic peoples' third party with full participation by labor, minorities, and every progressive grouping in the peoples' struggle. That's the nature of the battle we face today, and the first step is to defeat Bush. It's bitter medicine, but there's no sugar pill to take its place.
