Another forum that I belong to is exclusively about American politics, and has a lot of very savvy people on it -- from inside the Beltway, working for various senators, working for Congress, etc.

If you want to get rid of Bush, the word there is to follow Dean, even if you have to hold your nose. The one thing that people on that forum fear is third-party voting. Nothing wrong with it, as it sends a message. But not in this next election, in which the focus must be to get rid of Bush.
