I've known a good number of Republicans who are atheists who despised Jerry Falwell Sr., and would cringe at the notion that the GOP 'stood for Jesus' and 'family values,' whatever the hell that means. Fallwell Jr. has his own concept for that one!
They probably don't believe in souls. Just a bunch of hypocrites. Opportunists who don't care about anyone but themselves. They certainly don't believe in God, they just use religion to control others. They don't care about future generations, they just want to grab a quick buck.
