SBVT characterized itself as a non-partisan group both in the legal sense and in spirit, yet several prominent individuals who assisted SBVT also have had close ties to the Republican Party. According to information released by the IRS on February 22, 2005, more than half of the group's reported contributions came from just three sources, all prominent Texas Republican donors: Houston builder Bob J. Perry, a longtime supporter of George W. Bush, donated $4.45 million, Harold Simmons' Contrans donated $3 million, and T. Boone Pickens, Jr. donated $2 million. Other major contributors included Bush fundraiser Carl Lindner ($300,000), Robert Lindner ($260,000), GOP contributor Aubrey McClendon ($250,000), George Matthews Jr. ($250,000), and Crow Holdings ($100,000).
