I hate to be a nitpicker, but Politico is getting its generations mixed up:
Obama is the first Gen X Presidential candidate — for better and for worse.
He's the son of a baby boomer — his mother, Anne, was born in 1942 — and although his birth in 1961 puts him slightly ahead of the textbook mid-1960s start date of Gen X, he is the same age as the man who coined the term "Generation X," author Douglas Coupland.
