On Friday, Garrett Quinn pointed out two congressional races in which a Libertarian Party candidate received considerably more votes than the margin separating a winning Democrat from a losing Republican: Massachusetts' 6th District (48.3%-47.3%-4.5%** for Rep. John Tierney over Richard Tisei and Daniel Fishman), and Utah's 4th District (49.3%-48.1%-2.6%** for Rep. Jim Matheson over Mia Love and Jim Vein).

Last Wednesday, Brian Doherty also flagged Montana's race for U.S. Senate, where incumbent Sen. John Tester defeated the Ron Paul-endorsed Denny Rehberg 48.7% to 44.8%, while LP nominee Dan Cox received 6.5% of the vote. All three losing Republicans had significantly more libertarian credibility than maybe 90% of elected GOPers on the national level.

So are there any other "spoiler" accusations out there? At least four, probably more:

* Arizona's 1st Congressional District, where Democrat Ann Kirkpatrick beat Republican Jonathan Paton 48.4% to 45.7%, with Libertarian Kim Allen receiving 5.9% of the vote.

* Arizona's 9th Congressional District, where Democrat Kyrsten Sinema beat Republican Vernon Parker 48.2% to 45.4%, with Libertarian Powell Gammill garnering 6.4%.

* New Hampshire's 1st Congressional District, where Democrat Carol Shea-Porter beat incumbent Rep. Frank Guinta 49.7% to 46.0%, while Libertarian Brendan Kelly netted 4.3%. Editorialized the Andover Eagle-Tribune: "Perhaps Libertarians need to consider if their futile candidacies, which serve only to elect Democrats, are really in their long-term interests."

* Colorado's State Senate District 19, where incumbent Sen. Evie Hudak squeaked past Republican Lang Sias 46.9%-46.4%, while the LP's Lloyd Sweeney pulled down 6.5%. Commented former state GOP chair Dick Wadhams: " I think you have to go on the assumption that the majority of Libertarian votes would go to a Republican candidate if the Libertarian candidate was not on the ballot."

Any other national, state, or local LP "spoiler" accusations out there? List them in the comments, and I'll keep adding to this post.
