Check out the article "The GOP Primary Field in Buffy Villains" on this blog. It pairs the GOP candidates with the Buffy the Vampire Slayer villains they most resemble, and then explains why. Of course, I immediately wondered if this document could provide valuable clues to the personality types of the candidates (or the villains, if you prefer.)
Previously, in her article "Election 'o8", Mary Beth speculated about the Enneagram types of various political candidates. Mary Beth said she thought Fred Thompson might be a 5, an 8w9, or a 9w8. This article pairs Thompson with The Judge, and they really do sort of look alike. The article's description of the two as "a lethargic mess" who "didn't accomplish much" supports the theory that Thompson's personality has a 9-ish component. (Sloth is the vice associated with type 9.)
Mary Beth said Mitt Romney was a 3. The article pairs Romney with Mayor Richard Wilkins and says "They're both clever and generically slick politicians, programmed to appeal to middle America." If that's not type 3, I don't know what is.
Mary Beth said she didn't know what type Rudy Guliani was, but that various people were typing him as a 1 or a 7. This article pairs him with Angelus (the evil version of Angel), who is typed as a 3w4 on the Enneatrek site.
And last, but not least, I know you're dying for our insights on the personality type of Duncan Hunter. Mary Beth didn't speculate about him, and I don't know anything about him, but he is paired with Adam, who has a 5-ish/8-ish vibe to me. Seriously, when he walks up to a human boy, asks, "How do you work?" and then dissects him to find out, my heart just skips a beat. He is the only Buffy villain I have ever had a crush on.
