Perry
has made some mistakes . . .
1. Support for Trans-Texas corridor, as already mentioned.
2. He positively LOVES toll roads.
3. He signed a bill allowing tuition discounts for ILLEGAL ALIENS at Texas colleges and universities.
4. He issued an executive order mandating HPV vaccination for girls. (Note that this order had NO force of law behind it.)
On the other hand, he seems to favor holding the line on both taxes and spending, he's pro-RKBA, and he opposes both Obamacare and cap-and-tax. Despite his imperfections, the opposition has yet to come up with anyone better.
