The human rainbow in evidence throughout the Democratic National Convention events in Denver didn't exactly stretch over the Jefferson County Fairgrounds today, where Alaska governor and Republican vice-presidential candidate Sarah Palin spoke. I saw precisely three African-Americans in a crowd a volunteer estimated at 6,000 -- and two of them worked for the McCain-Palin campaign, while the third was a member of the media contingent. I also saw an Asian woman with a child, who wouldn't stand out in most crowds but did in this one. Still, the Caucasians present did represent a range of ages, genders and styles of dress, from a few biker types in full leather regalia (including one proudly sporting a Pluto the Dog T-shirt) to lots of guys wearing suit jackets and open collars (to make them seem like regular guys). That's diversity, Republican-style. -- Michael Roberts
