As reported by Jonathan Martin in POLITICO, Texas Gov. Rick Perry was a leader in putting state spending online:

“Grover Norquist, President of Americans for Tax Reform extrapolated by saying, ‘When I called around to governors in 2006 looking for good ideas that could travel, Perry explained that he was making his government transparent by putting all spending online,’ ‘That idea has now been adopted by 26-plus states. We took Perry's idea to other state legislators and governors.’”
