Naturally, I'll be spreading this again in 2012 if we hear a word about a possible Palin nomination (GOP suicide, naturally), but now it seems helpful to document the gross lies, incompetence and excuse-making of a shifty governor who couldn't be cute and personable enough to cover her inability to govern in a world of Wikis and fact-checking (I hesitate to say "bloggers" since I am, after all, merely linking to and summarizing The Atlantic).
The Lies of Sarah Palin
Palin lied when she denied having said that humans do not contribute to climate change; in fact, she had previously proclaimed that human activity was not to blame.
Palin lied when she claimed that Alaska produces 20 percent of the country's domestic energy supply; in fact, the actual figures, based on any interpretation of her words, are much, much lower.
Palin lied when she told voters she improvised her convention speech when her teleprompter stopped working properly; in fact, all reports showed that the machine had functioned perfectly and that her speech had closely followed the script.
EDIT: Uh, I should note that this type of behavior isn't particularly uncommon among politicians, and that I'm biased in that Palin's over-the-top self-righteousness and belief in self-fulfilling airs of competence puts me on edge with her.
