John J. Miller writes in the NY Times that it was the Libertarian vote (more than 3,000) that cost Thune the Senate seat in South Dakota; Thune lost the seat by 524 votes. This marks the third consecutive election in which the libertarian has cost the GOP a Senate seat. He also points out that it was the Green candidate who allowed Bush to win Florida (Nader took 97,000 votes from Gore); Bush won the state by 537 votes. Worth contemplating, this.
