I take it when you say "BB" ... you are using your lefty-lingo and saying "Bush-Bot". You are wrong. You are ignorant to Rush's show. Rush often disagree's with President Bush, such Big Spending, Border Issues. If Rush agrees with the pick, it is because it is his belief, not because is is a "BB".
Testing the wind...Rush knows this is unpopular and is fishing for a way to support Bush.
Or it could mean "Beltway Boy" couldn't it?
Either way, Rush is NOT.
