On March 8, the Georgia Libertarian Party, which nominates by convention, chose its 2014 candidates. The party is on the ballot for all the statewide offices, but not the district or county offices. The party nominated Amanda Swafford for the U.S. Senate seat. She has twice been elected to the Flowery Branch city council. The last time Georgia held a U.S. Senate election, in 2010, the Libertarian nominee received 2.69%.
On March 10, Roger Roots entered the Montana Libertarian primary for U.S. Senate. Since no one else filed, he will be the nominee. See this story about all the candidates who filed for the Montana seat. In 2012, the Libertarian nominee for the other Montana U.S. Senate seat polled 6.56% of the vote in a race in which no one received a majority.
Both the Georgia and Montana U.S. Senate seats are open; incumbents Max Baucus (Democrat) and Saxby Chambliss (Republican) aren’t running for re-election.
