Bush calls US "a nation of prayer"

First off, what does that even mean?

Secondly, I was taught that your piety was something you're not supposed to talk about. And it's certainly not something you boast so much that you're practically bragging about it. Why is it all of these right-wing thumpers always have to throw their religion in our faces? My guess is that Bush has 32 reasons... well, 32% reasons, anyway.
