Who is John R. Bolton?

Can we finally have a vote on John R. Bolton?  Who is this man that the Democrats hate and the Republicans waiver their dedication.  It seems that Senate Majority Leader Bill frist is confused after saying that there will be no vote and then reversing his decision after meeting with President Bush.  Bolton is a man that rightly criticizes the effectiveness of the U.N. since its tarnished reputation from both the Oil-for-Food Scandal and allegations of rape among peacekeepers.  I can tell you that I wouldn’t want the U.N. to do my accounting nor peacekeeping.  Perhaps we can either find the political muscle through Bolton’s nomination to either clean up the U.N. or help transition the U.N. without the United States as its financial backer.  Quotes on the Bolton range from calling him a right-wing extremist to being able to collaborate and bring new perspective to the U.N.  I hope we can finally get the U.S. out of the U.N. to preserve our integrity and sovereignty.
