Mitt Romney and I have many things in common. We were both schooled in Utah (no, I went to the "U"), together we saved the Salt Lake Winter Games, and we love science fiction. The difference is that Mitt loves crappy sci-fi.
Does taste in SF make or break a candidacy? I think it's a more valid factor than a candidate's haircut, waistline, or iPod playlist (current media staples, joined just now by desert island necessities. What's next? Which "Lost" character do you most identify with?). Charles Stross's "Glasshouse" and Jo Walton's "Farthing" would be my litmus test. Did you read them? Did you like them?
