"The Barr Factor"
Don’t miss Dave Weigel’s writeup of Bob Barr’s announcement of his candidacy for the Libertarian Party presidential nomination. I think this is a potentially significant turn of events as Barr, a former wingnutty member of the House GOP leadership, is an unusually credible LP standard-bearer and his biography is well-designed to attract the votes of conservatives who loathe the war and Barack Obama with equal passions.
Third party candidacies never go anywhere as candidacies but often wind up playing a substantial role in presidential campaigns nonetheless. Ralph Nader got only 2.7 percent of the vote in 2000, but that was enough to make a difference.
