Let's see who's ignorant.
He did that before running for president and got in trouble for it so I doubt he would ever do that again. Since then, he went out of his way to demonize undocumented immigrants. When he was going up against Bill White, the Houston Mayor who had asked the police to not check for immigration status of people on the street without an arrest, Rick Perry ran ads showing a police widow whose husband was killed by an illegal and blaming Bill White's "Sanctuary City" policy.

In 2010, he ordered the DPS (in charge of issuing driver's licenses) to ask for proof of citizenship for driver's licenses AND renewals. Anybody whose visa was going to expire within 6 months would be denied all together. Anybody who already had a license would have to show up in person to renew. Many legal immigrants also were denied and there was a lawsuit against him because many felt this was something the legislature could do.

Because of that, in 2011, he held the legislature for an emergency session so they could pass the law requiring the DPS to check immigration status and with that sealing the fate of many immigrants who already had driver's licenses and were driving safely on the road. I bet many of those were also college students who all of a sudden were left with no valid ID's. After graduating from college, what good is their little student ID?

So yea, Ricky did something right by accident, but he did a lot worse things to us. Has he defended CIR in any shape or form? No. You can praise Rick Perry because of what Obama did with DACA. Without DACA, I bet you'd be singing a different tune about Rick Perry. How would you get to school? How would you fly?
