In March, I suggested that the McCain campaign fire Mark McKinnon, its adman who had loudly told the press how much he loved Barack Obama and would not be able to bring himself to continue with the McCain campaign should the junior senator from Illinois win the Democratic nomination. Yesterday, McKinnon decided to step down from the campaign, telling Cox News Service “I just don’t want to work against an Obama candidacy” and that a President Obama “would send a great message to the country and the world.” McKinnon says he will still support McCain. My question is why he just doesn’t go work for the Hope Pope.
