Phil Cox

In 2019, Cox served as co-chair for Trade Works for America, a national coalition formed to pass USMCA.

Cox serves as Chairman of the Board of IMGE, a digital consulting and marketing firm, on the Board of Directors for the Senate Leadership Fund, and is a member of the Public Policy Council for the Michael J. Fox Foundation, which is a leader in the fight against Parkinson’s disease.

In 2018, Cox served as Chairman and senior advisor to super-PACs in support of candidates for governor and U.S. Senate, and managed Independent Expenditure campaigns on behalf of the RGA in a handful of governors races, including the only pick-up of the cycle in Alaska.  

Following President Donald Trump's election, Cox founded GuidePost Strategies, a federally-focused government and public affairs firm, along with former RGA Policy Director, Marie Sanderson. In 2018, former White House Legislative Director, Marc Short, joined GuidePost as a partner.

In 2015-2016, Cox founded and directed America Leads, the presidential Super-PAC supporting New Jersey Governor Chris Christie.

Following the 2014 cycle, The Boston Globe called him “a force for the GOP”, The Washington Times “a Republican Kingmaker”, and Politico named him one of its “50 Politicos to Watch.” 

From 2011-2014, Phil served as Executive Director of the Republican Governors Association, the senior political adviser to the 31 Republican Governors that held office at that time. During that period the RGA directed more than $250 million in support to candidates in all 50 states. During Cox's tenure, the RGA strengthened its majority, electing 31 Republican governors, with notable wins in traditional Democratic-leaning states like Massachusetts, Maryland, Illinois, and Maine.  

In 2010, Governor Haley Barbour, Chairman of the Republican Governors Association, hired Cox to help oversee the RGA’s political engagement in a half dozen states, including the expensive battlegrounds of Pennsylvania and Florida. 

In 2009, Cox served as Campaign Manager for Virginia Attorney General Bob McDonnell’s campaign for Governor. A year after Barack Obama won Virginia by 7 points, McDonnell enjoyed a 17-point victory over Creigh Deeds, resulting in a sweep of all three statewide offices. Following that victory, McDonnell appointed Cox as his Transition Director. 

From 2002 – 2005, Cox helped direct communications and fundraising for the Mercatus Center at George Mason University, and from 2006 – 2008 worked alongside Tim Phillips at Americans for Prosperity, directing AFP’s fundraising,  state chapter development, and issue campaigns. 

After graduating from the University of Virginia in 1996, from 1997 – 2001 Cox worked on a series of Virginia General Assembly campaigns, eventually helping to elect more than two dozen members. In 2001 he served as Campaign Manager for Lt. Governor John Hager’s campaign for Governor, and in 2005 helped direct Bob McDonnell’s successful campaign for Attorney General.
