The Senate campaign of Rep. Roy Blunt (R-Mo.) is featuring President Obama’s recent fundraising trip to Missouri in a new attack ad. 

The 30-second spot released Tuesday slams Secretary of State Robin Carnahan (D) as a “rubber stamp” for the “Pelosi-Reid-Obama liberal agenda.”

The spot uses images of Obama and Carnahan on stage together at a July 8 fundraiser in Kansas City, Mo. It ends with the voiceover saying Blunt will “work for Missouri, not Barack Obama.”

The Democratic Senatorial Campaign Committee hit back in a statement accusing Blunt of “adopting the Republican establishment playbook trying to nationalize the election.” 

Republicans are anxious to tie Carnahan to the president, and earlier this month signaled it would be a key part of their strategy. Obama’s approval rating in the state is less than 50 percent, and key parts of his legislative agenda are deeply unpopular there. He lost the state to Republican John McCain in 2008 by less than a point.
