Harper Polling routinely surveys the American political landscape, tracking the battle for control of the United States Congress and Governor’s offices across the country. Harper was the only Republican polling firm to accurately predict the outcome of the Massachusetts U. S. Senate special election of Senator Ed Markey in June 2013 and we precisely forecasted the 11% margin of victory for Cory Booker in the New Jersey U.S. Senate special election in October 2013.

In 2014, Harper was the only public pollster to correctly predict Tom Wolf’s landslide victory in the Democratic primary for Governor of Pennsylvania as well as his margin of victory in the general election. Harper also was the only public pollster to predict Thom Tillis’ 2% victory over Kay Hagan in the North Carolina Senate race. 

Respected, affordable, and accurate. Harper Polling is a unique breed in polling.


Brock McCleary, President

Prior to founding Harper Polling in 2012, Brock McCleary worked as a campaign operative, Capitol Hill aide, and party strategist.  While at the National Republican Congressional Committee (NRCC), Brock served as Polling Director and Deputy Political Director.

During his time as a House Republican 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 describing the historic success of the leadership team at the NRCC, famed political handicapper Charlie Cook said, “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.”

Brock is one of the country’s foremost experts on the political landscape of Congress.  Since 2010, the new faces in Congress outnumber the old ones and redistricting in 2011 overhauled the congressional map.  Few in politics understand the electoral footing that exists beneath Congress better than Brock.

As NRCC Polling Director, Brock took a non-existent polling department and made it into a robust operation that commissioned and analyzed over 200 polls in 100 congressional districts in 2012. For the first time ever, the NRCC began conducting polls in-house utilizing Interactive Voice Response (IVR) technology.  Brock used IVR polls for tracking competitive House races and testing party messaging.

 McCleary’s perspective on American politics and polling is regularly published in Politico, National Journal, Roll Call, New York Times, Washington Post, Philadelphia Inquirer andPittsburgh Post-Gazette.

Harper Polling offers a variety of survey research methodologies.

Interactive Voice Response (IVR)

The rise of automated IVR polling methodology is fueled by its undeniable accuracy and proficiency.  The affordability of IVR polling allows most budgets to utilize survey research.  Fast, concise and reliable results are the hallmarks of this brand of polling. 

Live Operator

Harper Polling also conducts traditional live-operator surveys.  This methodology is sometimes preferable for lengthier surveys that include a large number of demographic questions. These surveys call both land lines and cell phones.

Hybrid Sampling 

Using a “hybrid” or "mixed mode" sampling methodology, Harper Polling can conduct surveys that include cell phone respondents at a fraction of the cost of competitors.  Cell phone interviews are conducted exclusively through the use of live operators and land line interviews are conducted using the IVR automated system.
