We all thought it was down to a two-man field. Obama vs. McCain. But it's turned out to be a three-man race: Obama vs the Old, Honorable McCain and his political doppelganger the New, Unprincipled McCain.
Corsi has been referred to as a "conservative gadfly." But the word "gadfly" implies someone who is well intentioned and who seeks to provoke thought in others, not a lying, white supremacist, propagandist.
Corsi's biggest claim to fame is co-authoring the infamous Swift Boat Veterans for Truth. Judging from the shrill and paranoid tone of his latest effort I get the impression Obama has really scared these guys this time.
