McCain adviser steps off, not under, the bus

In one of the more genteel departures from a political campaign, media consultant Mark McKinnon made good on his vow to exit the John McCain campaign because he doesn't want to attack Barack Obama (whom he admires) in the general election.

McKinnon - once a Democrat who later worked on both of the presidential campaigns of George W. Bush - experienced no such vapors in 2004. According to a 2005 Broadcasting & Cable article, "He mounted a brutally effective ad campaign against John Kerry in 2004, which included the 'Windsurfing' spot portraying the Democratic candidate as a rich dilettante." Watch the spot below.



"Under the bus" rating: on a scale of one to five, McKinnon gets a transfer pass.
