I will say this: those of us who hold certain issues as paramount, whether it be border security, abortion, or (in my case) national defense/military, should be careful. Frauds and charlatans target people who are emotionally caught up in an issue and want to believe that someone can "fix" things. Larry Klayman bamboozled a whole bunch of us into thinking he was really concerned about corruption in the Clinton era; what Klayman was REALLY concerned about was the Klayman bank account. Bay Buchanan seems to be inordinately interested in fundraising as well. I haven't figured out if Keyes is part of the scam or a victim of believing his own press, but I don't trust him, either. And I am also not certain that Curt Weldon is as interested in getting to the truth of Able Danger as he is in slamming Rumsfeld and getting on talk shows.
It pays to be careful about giving money. Not all who spin a good story are ethical.
