I just heard the final 20 minutes of Alan Keyes on NPR's Fresh Air.
I am absolutely convinced, in a way that no written account could ever do, that the man is certifiably insane. He spouted lines and held positions that no sane person could ever espouse. He even repeated the assertion that his opponent's position on abortion (pro-choice) was the "slave holders' position." The man is an absolute loon.
Illinois, Barack Obama will - without a doubt - be your next Senator.
