...for example, Brownback:
"We should be able to say one nation Under God and the flag salute and not be worried about anybody suing us."
Well, unless your idea of the "flag salute" is, say, shooting a child in the face with a shotgun, you're unlikely to be sued for that. As for the "Under God" thing, about the only time that might happen is if you have a custodial role in public schools. Unlikely even then.
I'm sure few of the fine folks of Iowa who gave him his "biggest applause line" have ever actually held off saying "Under God" or saluting the flag because they feared some dirty liberal was going to sue them for it. Still it's very exciting!
