Salon.com has an article today about the similarities between President Obama and Spock from Star Trek, from his mixed race heritage to his passion for logic:

"Like Spock, part of what makes Obama so appealing is the fact that although he's an outsider -- "proudly alien," as Leonard Nimoy once put it -- he uses that distance to cultivate a sense of perspective. ... Nimoy's alter ego was the harbinger of a future in which logic would reign over emotion, and rational thought triumph over blind faith. He was a digital being in an analog world; the Pied Piper who led our generation into the Silicon Age."

Also, totally unsurprisingly but satisfyingly, it seems Obama himself is down with Trek. As Leonard Nimoy attested during the presidential campaign:

"About a year and a half ago, I was at a political event. One of our current campaigners for the office of president of the United States saw me -- and as he approached, he gave me the Vulcan hand signal." You can practically hear Nimoy's eyebrow raise. "It was not John McCain."
