MT GOP Upset Over Libertarian Candidate's Role

The Republican lost and the Libertarian drew a lot of votes

U.S. Senate Libertarian candidate Dan Cox will tell you that it was never his intention to be a spoiler in one of the most closely watched races in the nation.

He equally disliked both of his opponents' records.

But the nearly 30,000 votes Cox garnered in Tuesday's general election were 10,000 more than the difference between Democratic incumbent Sen. Jon Tester and his Republican challenger, Rep. Denny Rehberg.

Montana Republican Party officials say those votes were the difference in the election, and they are challenging some last-minute advertisements.
