Lord willing, I think Perry will announce at this event: http://theresponseusa.com
I think you're playing up the religious angle too much. Earlier today, he said it comes down to whether his donors can pledge the money and resources he needs. He's actually getting together tonight with like 30 or 40 donors behind closed doors to discuss whether he should or can run. It's a situation that's foreign to him - he's used to people being able to give however much they want to give in Texas races, but in a Presidential race, there's a limit of $2,500.
I know Perry brought up God somewhere, but it's going to come down to what those 30 or 40 people decide tonight. If they tell Perry that they can go out and get enough other people to write $2,500 checks, then he'll run.
