A newly released TV ad from Senate Minority Leader Mitch McConnell hammers his Democratic rival over her support for President Obama, in the latest attempt to use the president’s unpopularity in Kentucky to weigh down her campaign.

The McConnell ad cites Alison Lundergan Grimes’ support of Obama in 2008, and then mentions ensuing controversies – over the IRS, policies toward the coal industry, ObamaCare, Benghazi and other issues.

“After all this, Grimes still supports Obama. Is there any doubt how she’d vote in Washington?” the ad says.

Grimes, meanwhile, has portrayed McConnell throughout the race as a Washington insider who has left Kentucky behind. The charge was highlighted in a recent TV ad accusing McConnell of skipping Senate committee meetings. The McConnell campaign calls the ad misleading and points to the senator’s near-perfect voting participation rate in the Senate.

McConnell has a slight lead in the race. The latest CNN/Opinion Research Poll shows him up 50-46 percent, with two months until Election Day.
