2008 lieutenant gubernatorial bid
Pittenger defeated three other candidates in the Republican primary on May 6, 2008, becoming his party's nominee for Lieutenant Governor of North Carolina with 59% of the vote. On May 27, 2008, he resigned from the Senate to focus on his campaign. He lost the general election to fellow State Senator, Democrat Walter H. Dalton, 51%–46%.
After Sue Myrick announced her retirement as the Representative of North Carolina's 9th congressional district in early 2012, Pittenger announced that he would run to replace her. He failed to win the primary outright on May 8, 2012, but finished first with 32% of the vote in the 11-candidate field. In the primary runoff election held on July 17, he defeated former Mecklenburg County Sheriff Jim Pendergraph, 53%–47%. Pittenger won the general election on November 6, defeating Democratic Mecklenburg County Commission Chairwoman Jennifer Roberts, 52%–47%. He lost the district's share of Mecklenburg County, but ran up huge margins in the Union and Iredell portions of the district. It was the closest a Republican had come to losing the district since 1986. He took office in January 2013. On December 2, 2013, Pittenger introduced the Kilah Davenport Child Protection Act of 2013, which became. The law broadens the coverage of current laws that address domestic assaults by certain repeat offenders. It also requires the United States Department of Justice to write a report on child abuse prevention laws in all U.S. states and territories, "with a particular focus on penalties for cases of severe child abuse."
Pittenger considered running for the U.S. Senate but instead ran for reelection to the House. In the Republican primary, he defeated Michael Steinberg, a candidate for the seat in 2012. No Democrat filed to run for the seat, making this district the only one in the state not contested by both major parties in 2014. There was an unsuccessful write-in campaign for candidate Shawn Eckles of Iredell County.
2016 election
The 9th was significantly redrawn after a federal court threw out the previous map as an unconstitutional racial gerrymander. It was pushed well to the east, stretching from southeast Charlotte all the way to Fayetteville and the Sandhills. Baptist pastor Mark Harris challenged Pittenger in the 2016 Republican congressional primary, losing that contest by 134 votes. Pittenger defeated Christian Cano in the general election.
2018 election
Pittenger faced Mark Harris in a rematch of the 2016 Republican primary. On May 8, 2018, Harris defeated Pittenger with 48.5 percent of the vote to Pittenger's 46.2 percent, although allegations were later raised about illegal activities by the Harris campaign. Pittenger was the first congressional incumbent to lose his primary election in 2018; the second was Mark Sanford. After Harris became the apparent winner in the November 2018 general election, the result was not certified due to electoral fraud, and a new special election was planned. Pittenger declined to run in the special election.
Pittenger rejects the scientific consensus on climate change. In 2006, he sent a book called The Skeptical Environmentalist, published in 1998, to his colleagues in the North Carolina Senate.
Health care
Pittenger supported the American Health Care Act of 2017, which would repeal the Patient Protection and Affordable Care Act, also known as Obamacare. On May 2, 2017, Pittenger defended a provision of AHCA that allowed states to end requirements that insurers cannot discriminate against individuals with pre-existing conditions. Pittenger said that Americans who have or develop pre-existing conditions "should just move" to a state without the waiver.
Race relations
On September 22, 2016, in the wake of protests over the shooting of Keith Lamont Scott, Pittenger said that the violence in Charlotte stemmed from protesters who "hate white people because white people are successful and they're not." The remark drew immediate international condemnation as racist. Fellow North Carolina congressman G. K. Butterfield called the remark "devastatingly ignorant and divisive." Pittenger apologized, saying that his "intent was to discuss the lack of economic mobility for African Americans because of failed policies."
National defense
Pittenger voted for the two-year budget plan that became law on February 9, 2018, citing the lack of options to increase military spending to provide for required training and maintenance.
