Barney also wrote and produced ads and mail for Governor Chris Sununu (NH) and Congressman Trey Hollingsworth (IN), and worked on independent expenditure and issue advocacy campaigns in support of Senator Pat Toomey (PA), Senator Rand Paul (KY), and Congressman Jim Banks (IN), among others.

Jon Kohan | Partner

Jon Kohan is a Partner at Jamestown Associates. Prior to re-joining the firm in January of 2017, he led some of America's most nationally watched and fiercely contested races over the past two cycles.

Most recently, Kohan led Senator Kelly Ayotte’s re-election effort in New Hampshire, which finished as the most expensive per capita U.S. Senate race ever – totaling nearly $130 million spent when the dust settled. In this capacity, he managed a $17.7 million budget and led a team of 35 full-time and over 200 part-time staff that raised over $14 million, served 130 million targeted impressions on TV and online, and made 1.3 million voter contacts in a state with roughly the same population.

Prior to the Ayotte campaign, Kohan served as Senator Joni Ernst’s Deputy Chief of Staff, helping to manage her office and political activities. In 2014 he managed Ernst’s electrifying victory in Iowa, earning him Campaign Manager of the Year honors from the American Association of Political Consultants.

In 2013, Kohan managed Congressman Mark Sanford’s impressive come-from-behind special election victory in South Carolina, despite being outspent two-to-one. Campaigns & Elections Magazine named him a Rising Star after orchestrating Sanford’s astonishing victory. He went on to serve as Sanford’s Chief of Staff, managing 16 staffers across three offices. Sanford was the only member of the SC congressional delegation to run unopposed in 2014, after facing 16 opponents the year prior.

From 2011-2012, Kohan worked at Jamestown as an account executive, primarily focused on media production and independent expenditure work, as well as assisting campaigns on the ground in South Carolina, Indiana, New Jersey and other parts of the country.

From 2005-2011, Kohan worked on campaigns in New Jersey and served as a staffer in the U.S. House of Representatives.

Ben Hartman | Executive Vice President

Ben Hartman joined Jamestown Associates as the firm’s Executive Vice President after successfully managing Governor Matt Bevin’s campaign in Kentucky. With Ben’s help, Gov. Bevin became only the second Republican to hold that office in 44 years, and his running mate, Lt. Gov. Jenean Hampton, became the first African-American ever to be elected statewide.

Before the big win in Kentucky, Ben was the Campaign Manager for Texas Congressman Randy Weber, who replaced retiring Congressman Ron Paul, as well as U.S. Senate candidate Milton Wolf in Kansas. In addition, he worked as a field operative for Congressmen Michael McCaul and Bill Flores in Texas, and managed the Victory Operation of the Connecticut Republican Party.

Among Ben’s biggest accomplishments since joining Jamestown was assisting the independent expenditure effort that helped flip the Kentucky House of Representatives from Democrat to Republican control for the first time since 1921.
