Twice in the last two weeks has Time magazine devoted a page to Mark Halperin's oddsmaking on who will be the Republican nominee -- the May 23 issue (page 35) and the June 6 issue (page 16). Twice, there's been no mention of Herman Cain. The GOP cast of contenders is lily-white. This seems odd, since Cain participated in the first presidential debate on May 5 to high praise and formally announced on May 21. Are Time and Halperin racists? They can't say they're unaware that Cain is running.
