I can confirm that the attack ads in Mississippi run by "All Citizens for Mississippi" were funded by Senate Republicans, including Senators Mitch McConnell, John Cornyn, Rob Portman, Bob Corker, and Roy Blunt. It appears our Senate Republican leaders are willing to risk losing a Senate majority so long as they can get their own re-elected. Yes folks, it is true. I can confirm what we all suspected.
The advertisements attacked Mississippi State Senator Chris McDaniel and painted conservative Republicans and tea party activists as racists. According to documents filed with the Federal Elections Commission, All Citizens for Mississippi received funding from a Haley Barbour backed group called Mississippi Conservatives.
Mississippi Conservatives, in turn, was funded in part by Sally Bradshaw of the RNC's Growth and Opportunity Project, former RNC Chairman and Mississippi Governor Haley Barbour, the United States Chamber of Commerce, and the political action committees created for Senators Mitch McConnell ($50,000), John Cornyn ($50,000), Rob Portman ($25,000), Bob Corker ($25,000), and Roy Blunt ($5,000).
Interestingly, Sally Bradshaw and Henry Barbour (Haley Barbour's nephew) worked on the autopsy of the 2012 GOP loss.
