Not Texas, Rick Perry.
Incorrect. It actually began with Guv Bill Clements. Because NAFTA was coming he put the ball in motion giving the task to the transportation think tank at UT to come up with a plan. The report was published while GW Bush was Guv but was set aside because he would be running for prez.
Before the TTC project could go forward Texas first had to have a state referendum ending "pay-as-you-go" which was in the constitution. That would be very controversial so they decided to let the next Guv handle it.
