Battle for the Big Sky delves into one of the few competitive races of the 2012 election: the US Senate campaign in Montana. Author David C.W. Parker was granted exceptional access by both candidates over the 21 months preceding the election, allowing him to tell the story of the race in rare and fascinating detail, while also exploring the impact of Citizens United and so-called "e;dark money"e; on the campaign. The Montana setting offers readers a view into the rising political influence of the West, the importance of "e;place"e; in politics, and the impact of congressional styles and constituent relationships on campaigns and elections. Parker skillfully weaves political analysis into his narrative and places the race in the broader context of congressional elections and the research literature.
