Political consultant Rob Gray was senior advisor and media strategist for the only political campaign Mitt Romney has ever won: the 2002 gubernatorial election. Gray, a Weld/Cellucci aide, friend of Karl Rove, and regular Romney consultant, has just signed on with the enemy, from Mitt's perspective. John McCain announced today that Gray will be a senior advisor focusing on communications and political affairs in New England for McCain's Presidential "exploratory" committee.
