Yes, he came to fight. I say more power to him.
He came in a fighting mood, because like thousands of other leaders in DC, he reads FR...and he is getting damn sick and tired of seeing every conservative leader worth spit being trashed by the "Bush FR Response Team".
He has friends...friends to whom he is loyal. He was simply doing what any honorable man will do when his friends are continuously attacked with smears...he is fighting back.
God help this country if the fighters like Mark Levin are in some way marginalized by attacks by the political establishment...there wouldn't be anyone left who cared much about anything in Washington beyond the next election.
