Because I enjoy each new revelation of as-yet unimagined levels of mendacity.
Various bloggers were described in the NYT as furious with Bill Clinton for having noticed not only that Obama is black but for having so much as implied that voters in South Carolina may have noticed it too. Black voters would vote for a brown paper bag and Clinton had the audacity to hint they would.
Humorously the question put to Jackson was whether he was offended by Clinton having mentioned that he had twice won the South Carolina Democratic primary. Can't get more offensive than that. Jackson, having had Clinton wipe the floor with him politically over the 1992 Sista Souljah remarks about killing cops, chose not to be offended.
In a year Barack Obama will be a half-remembered bump in the road on Bill Clinton's way back to the White House.
