Maybe Barr's onto something

I guess he won't be the last.

A former Georgia congressman who helped spark President Clinton's impeachment has quit the Republican Party to become a Libertarian, saying he is disillusioned with the GOP on issues such as spending and privacy.

Bob Barr, who served eight years as a Republican congressman before losing his seat in 2002, announced Friday that he is now a "proud, card-carrying Libertarian." And he encouraged others to join him.
