Harper President Brock McCleary is one of the most recognized pollsters and political strategists in the country. Prior to founding Harper, Brock served as the Polling Director and Deputy Political Director for the National Republican Congressional Committee (NRCC) as Republicans won historic majorities in the U.S. House of Representatives in 2010 and 2012. The firm’s namesake is Brock’s daughter Harper.

Harper Polling has enjoyed substantial growth and a winning track record since its founding in 2012, conducting hundreds of surveys in over 40 states and nationally.

Brock McCleary serves as pollster and consultant to Members of Congress, state and federal campaigns, political party committees, independent expenditure units, and a wide array of nonpartisan public policy groups at the federal and state levels.

Brock previously served as Polling Director, Deputy Political Director, and Northeast Political Director at the National Republican Campaign Committee (NRCC). During his time as a House Republican campaign strategist, the NRCC picked up 63 seats in the House of Representatives in 2010, the largest gain since 1948, and secured the two largest majorities for Congressional Republicans since World War II.

In 2012, Brock was responsible for the Republican House campaigns challenging sitting Democratic incumbents. On Election Day 2012, President Obama was comfortably reelected and 13 Republican Congressmen were defeated. Despite that, 10 Republican challenger campaigns surprisingly defeated sitting Democrats to help preserve the GOP’s majority in the House of Representatives.

In 2017, Brock served as the General Consultant for the NRCC’s victorious $8 million Independent Expenditure Unit in Georgia’s 6th Congressional District, the most expensive, high-stakes special election in history.

Brock is one of the country’s foremost experts on the political landscape of Congress. His work on redistricting efforts in 2011 and a high volume of Congressional polls each election cycle provide Brock with a unique understanding of the electoral footing beneath the U.S. House and Senate. 

Prior to founding Harper Polling, Brock McCleary worked as a campaign operative, Capitol Hill aide, and public affairs consultant. He previously served as Communications Director for Congressman and Chief Deputy Whip Patrick McHenry of North Carolina. He began his career in 1998 as the Deputy Coalitions Director for Pennsylvania Governor Tom Ridge’s reelection campaign. He served as Political Director of the New Jersey Republican Party and as a consultant to congressional and state legislative races in Pennsylvania and New Jersey, before heading to Washington, D.C.

Brock is an RIVA-trained focus group Moderator. In 2010, he was presented with the “Rising Star” Award by Campaigns & Elections magazine.

“Chairman Pete Session’s NRCC, led by Executive Director Guy Harrison, Communications Director Paul Lindsay, Political Director Mike Shields, and Polling Director Brock McCleary, correctly calculated early on in the cycle that offense was the best defense.  Their early attacks to encourage Democratic retirements helped create a GOP open-seat advantage and eventually forced Democrats to spend millions of dollars defending seats in places like Connecticut, Rhode Island and southern Illinois.”-Famed Political Handicapper Charlie Cook

Focus Groups

Harper Polling conducts focus groups; President Brock McCleary and Director of Research & Polling Victoria Waddail are RIVA-trained focus group moderators. Focus groups allow for deeper exploration of a particular topic or question and often provide an opportunity to elaborate and fine-tune messaging based on the findings of the survey research. This qualitative methodology allows for open discussion with and observation of a cross-section of the target population. We work with professional research facilities to recruit participants and conduct the focus group.
