I have many registered Dem friends who get their information from MSM and know very little of what is going on. They are the people who put approval ratings high for people or policy that third wayers love to quote on here. They are not Republicans, and don't vote Republican, but they vote with the party because that is supposed to be in line with their values. They don't really take the time to dig into the issues.
I had a friend--who would definitely score on the liberal side of the scale--bring up how we need to "strengthen Social Secrurity" because it was going broke. I asked him where he got that information. Turns out he had listened to a segment on NPR (he hadn't really noticed as it had moved slowly right politically). Once I told him the truth, he was angry that he had been duped by the propaganda. It was an easy argument.
I think education is the most important thing we can do. If we educate our circle of acquaintances, we can effect change. I would like somewhere a sort of handout or even a small business card sized thing I can give to people. Also a short bio of Senator Sanders would be nice as I don't think he's even on the radar yet. Showing that he is one of the last honest politicians and letting him run a campaign like Robert Redford in The Candidate. He has the truth on his side (as do we), and that is his most powerful weapon. It would be a great way to start now so people begin paying attention.
I think that is the most important thing this group can do.
