Her district includes constituents in Mecklenburg county. Carney is a homemaker from Charlotte, North Carolina. In 2002 Carney defeated Libertarian Daniel Elmaleh in the general election.
She had previously served on three terms on the Mecklenburg Board of County Commissioners, serving as vice chairman several times. Carney had an unsuccessful run for school board in 1995. During a late night House session on July 2, 2012, Carney mistakenly cast the deciding vote to override Governor Beverly Perdue's veto of Senate Bill 820, granting authority to make hydraulic fracturing legal in North Carolina.
A longstanding House rule that disallows changing of a vote if the vote changes the outcome of the bill prevented Carney from correcting her electronic vote to reflect her intended position.
Married Gene Carney; 5 children.
