Barry Ashlin Williamson (born ca. 1957) is an American attorney who served as a Republican member of the Texas Railroad Commission from 1992-1999. Originally from Arkansas, Williamson defeated the appointed incumbent Lena Guerrero, a Democrat in 1992 to win a seat on the 3-member commission.[1]
Williamson did not seek a second term on the Railroad Commission in 1998, but he instead ran unsuccessfully in the Republican primary for Texas attorney general. He lost a runoff election to John Cornyn. A third candidate eliminated in the primary was Tom Pauken, the former state party chairman. Cornyn then defeated the Democratic former attorney general Jim Mattox in the 1998 general election.
In 2010, Williamson served as campaign chairman for Republican Railroad Commission nominee David J. Porter, a Certified Public Accountant from Midland and Giddings, who upset incumbent Victor G. Carrillo of Abilene, Texas, in the party primary. Porter faces the Democrat Jeff Weems in the November 2010 general election. Williamson is also a former resident of Midland as well as Dallas, Texas.
