Diversity in Campaign Staffs
Courtesy of Matthew Yglesias, who in turn got the following from Ann Friedman, a graph here to show the racial diversity of the campaign staffs of many of the top contenders for President.

Really, is this all that suprising? Well, sort of. What's shocking is that apparently Giuliani's staff is 100% white, which is something one would think you'd have to actively try to achieve given the American landscape these days. And I'll just leave the fact that Republican staffers are much whiter than their Democratic counterparts on its own - no explanation necessary, as many of the GOP candidates are still playing the 'scary brown people' card, even in 2007.
Of course, Matthew Yglesias points out that Rudy is plenty diversified:
...only Giuliani among the major contenders has child molesting priests and mobbed-up former police commissioners in his retinue. It's only diversity in the racial and gender senses that he's lacking.
