Matt Taibbi in Rolling Stone:
It may be the hardest thing you ever do, for Michele Bachmann is almost certainly the funniest thing that has ever happened to American presidential politics. Fans of obscure 1970s television may remember a short-lived children's show called Far Out Space Nuts, in which a pair of dimwitted NASA repairmen, one of whom is played by Bob (Gilligan) Denver, accidentally send themselves into space by pressing “launch” instead of “lunch” inside a capsule they were fixing at Cape Canaveral. This plot device roughly approximates the political and cultural mechanism that is sending Michele Bachmann hurtling in the direction of the Oval Office.
Bachmann is a religious zealot whose brain is a raging electrical storm of divine visions and paranoid delusions. She believes that the Chinese are plotting to replace the dollar bill, that light bulbs are killing our dogs and cats, and that God personally chose her to become both an IRS attorney who would spend years hounding taxpayers and a raging anti-tax Tea Party crusader against big government. She kicked off her unofficial presidential campaign in New Hampshire, by mistakenly declaring it the birthplace of the American Revolution. “It's your state that fired the shot that was heard around the world!” she gushed. “You are the state of Lexington and Concord, you started the battle for liberty right here in your backyard.”
