Have you ever noticed how political conservatives, and people who love our country, shout "USA! USA!" at rallies? Have you ever heard liberals shout that? What did/do they yell at Obama rallies? "O-ba-ma!" What did they yell at McCain rallies? "USA!"
I think that says something.
And I think it says something when military personnel shout "USA", rather enthusiastically, when cheering for President Bush.
