Here's an interesting tidbit from Rick Perry's past to keep an eye on. In the mid-1990s, the presidential candidate owned stock in a video rental store chain whose hardcore porn offerings drew the ire of conservative groups, according to a 2006 report on a liberal Texas blog. That item was resurrected by several liberal websites this week.

Burnt Orange Report, a site founded by a Democratic activist, reported in 2006 that Perry's 1995 financial disclosure showed he owned between $5,000 and $10,000 in stock in the company Movie Gallery. He was at the time state commissioner of agriculture.

Why is that significant? Because the now-defunct Movie Gallery, once a competitor to Blockbuster, was known for offering XXX porn rentals along with conventional Hollywood fare. (FireDogLake offers a useful sampling of titles here.)

Ironically, it was the social conservative crusaders at the American Family Association -- the very group that helped organize Perry's stadium prayer rally this month -- who spent years on an anti-porn campaign targeting Movie Gallery. AFA was actively targeting Movie Gallery both before and after Perry owned the stock; at one protest event outside Movie Gallery's Alabama headquarters in 2000, AFA members held signs reading "Serve God or Serve Money," "Pornography hurts families," and "Porn dishonors mothers."
