Culberson won a surprisingly modest 59% of the vote in 2006 in what is otherwise a normally strong Republican district. He was still favored to win in 2008, given the 2006 anti-Republican trend and the normally Republican voting trend of this mainly suburban district, which is among the most affluent in the nation. Skelly, a former executive of Horizon Wind Energy, earned an MBA from Harvard after serving in the Peace Corps. He currently serves on Houston Mayor Bill White's Green Building Advisory Committee. Culberson defeated Skelly 55.9–42.3%.
