Brad Rogers Carson (born March 11, 1967) is an American lawyer and politician from the state of Oklahoma who served as the Acting Under Secretary of Defense for Personnel and Readiness from 2015-16. In that role, he initiated a number of notable reforms to include opening up all combat positions to women, open service by transgender service members, and new recruiting and retention practices. A member of the Democratic Party, he served in the United States House of Representatives from 2001-05. He served as Undersecretary of the Army from 2014-15 and as General Counsel of the Army from 2012-2014.

In 2004, Carson sought the open U.S. Senate seat being vacated by retiring Republican Don Nickles. Although he easily won the Democratic nomination, he faced a tough general election contest with Coburn, who had won the nomination by an unexpectedly large margin. Carson described himself as a Conservative Democrat. Carson distanced himself from the national Democratic Party on most public policy matters. He portrayed himself as more moderate than his Republican opponent. Coburn, by contrast was one of the "true believers" in the 1995 Republican House freshman class and its Contract With America. This race was considered one of a handful of competitive races for the U.S. Senate in 2004.  Both Carson and Coburn were fairly conservative on social issues. For example, Coburn and Carson both presented themselves as supporting the traditional definition of marriage as "a union of one man and one woman" in the gay marriage debate. Although registered Democrats outnumbered registered Republicans in Oklahoma by almost 2 to 1 at the time, most Oklahoma Democrats are quite conservative by national standards.  By many accounts, the 2004 U.S. Senate campaign between Carson and Coburn was one of the most partisan races of that year. Coburn claimed that a vote for Carson was a vote for Democrats such as Tom Daschle, Hillary Clinton and Ted Kennedy. Carson was also hampered by George W. Bush's tremendous popularity in the state (the John Kerry campaign made virtually no effort in Oklahoma). In the November election, Coburn defeated Carson by a large margin, 53 percent to 42 percent. While Carson trounced Coburn in the 2nd District, Coburn swamped Carson in the Oklahoma City metropolitan area and the closer-in Tulsa suburbs. Coburn won the state's two largest counties, Tulsa and Oklahoma, by a combined 86,000 votes -- more than half of his overall margin of 166,000 votes.  Despite Carson's loss, election analyst Stuart Rothenberg called the Carson campaign one of the four best run campaigns in the nation in 2004. The Weekly Standard called him "The Perfect Democrat" After the election, Carson wrote an article for The New Republic which was the subject of much discussion.
