"but don't boo someone just because they are A.) a liberal"
Are you serious? Booing someone because they are liberal is the least I would do, especially Tom Brokaw. My two sons were there last night at the game and they booed at the top of their lungs. I'm so proud of them...a chip off the ol' block!
My two kids were sitting with me -- they boo'd along with my son's friend and everyone else in our section. We are Bush Country in our section!
