A conservative group is running a pre-emptive television ad attacking Democrat Alison Lundergan Grimes, who is pondering a possible campaign against Senate Minority Leader Mitch McConnell.
The ad links Grimes to President Barack Obama by calling her the president's "cheerleader" in Kentucky.
Kentuckians for Strong Leadership says it put up $260,000 to run the ads in the Louisville, Lexington and Paducah markets. The ad says Obama and Senate Majority Leader Harry Reid are looking for senators to "jam through" Obama's agenda.
Kentucky Republicans routinely try to connect Democrats with Obama, who lost the state in his successful runs for the presidency. Grimes' political adviser Jonathan Hurst says the ad shows McConnell's allies are worried about next year's election.
