Controversy arose late in the 2008 elections as the Billings Gazette reported Montana Democrats as breaking campaign disclosure laws. A report came out identifying Democrats as calling voters anonymously to attack the republican candidate Jack Sands. 
The 2012 elections were identified by prominent members of the Party as being one of the most important elections in the Party's existence. The Party wished to re-elect Montana's U.S. Senator in Jon Tester. In addition to re-electing Jon Tester, the Party hoped to retain a number of other offices. Jon Tester believed it would not be hard to get Democrats of the State to the polling booths in early November 2012. The Senator believes the results of the 2010 elections should be enough for Democrats to come out in large numbers this time around.  During the election, Jon Tester was elected over his Republican challenger, and the victory by Steve Bullock meant that Democrats retained the office of governor after Brian Schweitzer was prevented from running again due to term limits.
