In the 2004 General Election, the CNN exit poll claims that Cubin won 76% of Republicans, 42% of Independents, and 18% of Democrats. The partisan split there was 53% Republican, 25% Democrat, 22% Independent. She ran 19% behind Bush amongst Republicans, 12% behind him amongst Independents and 9% behind him amongst Democrats.
Barbara Cubin has another serious opponent this year and his name is Gary Trauner. Gary has $205,914 on hand and has spent $241,693 so far.
With Cubin's weak showing in 2004, a vastly popular Democratic Governor on the ballot in 2006, and the whole thing about Republicans being in bad shape in general, Cubin is a lot more vulnerable than we know right now. Given the right momentum, Dick Cheney's Representative in 2007 could be a Democrat.
