The American Chemistry Council is running a TV ad in Kentucky promoting Senate Republican Leader Mitch McConnell as a leader who knows how to get results in Washington.
The McConnell ad comes at a time when the five-term incumbent is being attacked by GOP primary foe Matt Bevin. The new ad is running in Louisville, Lexington and Bowling Green.
American Chemistry Council spokeswoman Anne Kolton said the group is running similar TV spots this summer on behalf of Democratic Sens. Kay Hagan of North Carolina and Tom Udall of New Mexico and Republican Reps. Fred Upton of Michigan and Mike Simpson of Idaho.
Kolton said the organization is spending "six figures" to run the McConnell ad that will remain on the air for three weeks.
McConnell's campaign is also taking to the postal service to attack Bevin, calling him a "snake oil" salesman in a new mailer.
Bevin, a Louisville businessman, Bevin is slamming McConnell for "failed leadership" over nearly three decades in the Senate. McConnell has labeled his challenger "bailout Bevin" in an ad that references a $200,000 government bailout for a Connecticut company his family owns.
The winner of the McConnell-Bevin matchup will likely face Democratic front-runner Alison Lundergan Grimes, Kentucky's 34-year-old secretary of state, in the 2014 general election.
