Callie Shell has been following and photographing Barack Obama for Time since the beginning of the campaign. You can see some of her work here and, especially, here. I particularly love the photo of Obama doing a pull-up moments before delivering a speech. There's a matter-of-fact coolness about it. Glamour too, as Virginia Postrel could doubtless confirm. Actually, the Obama who appears in - or is presented by - many of Shell's pictures is, to my mind, strikingly reminiscent of a star such as, say, Paul Newman.
