One McCain-Feingold does more damage to the GOP than a dozen Bob Barr's ever could.
I don't disagree with this, but it doesn't change the facgt that we are a two party nation. Losertarians are either a non-factor or they are spoilers who help Democrats, as Barr did for Obama in Indiana and North Carolina.
Actually, I think if Barr had somehow gotten elected and implemented his "conservative" agenda on America (immediate withdrawl from Iraq, repealing the Patriot Act, repeal of the Defense of Marriage Act, etc., it would do far more damage to conservatives and to the nation than dozen McCain-Feingold bills on campaign finance regulations would do.
