Here's an article from the Houston Chronicle showing that Rick Perry's prayer rally is already being used for political purposes.
Gov. Rick Perry’s office insisted that the Aug. 6 prayer rally he initiated was “apolitical.”
But less than two weeks after thousands of people attended The Response in Reliant Stadium, the founder of the American Family Association sent out an email to prayer-rally registrants touting Champion the Vote, “a friend of AFA whose mission is to mobilize 5 million unregistered conservative Christians to register and vote according to the Biblical worldview in 2012.”
Yeah, it was totally apolitical. That's why the Rev. Don Wildmon said in the e-mail, sent to the 30,000 participants of "The Response"
The Response was just the beginning of a nationwide initiative to return America to the principles on which she was founded, with God at the center of our nation.
So who is going to be telling these 5 million unregistered (but soon to be registered) conservative Christians how to vote "according to the Biblical worldview in 2012"? Surely, there couldn't be a Republican bias to those recommendations.
Never underestimate the the reach of the conservative Christian movement.
