Senate Minority Leader Mitch McConnell (R., Ky.) has put together a TV ad using President Obama’s claim that his ‘policies are on the ballot” to attack his Democratic opponent, state secretary of state Alison Lundergan Grimes.

“Barack Obama himself has made abundantly clear that a vote for Grimes is a vote for in favor of his liberal policy agenda,” McConnell campaign spokeswoman Allison Moore said of the ad.

McConnell isn’t the first Republican to make hay out of Obama’s comments. Andrew Johnson notes that Scott Brown is already using it against Senator Jeanne Shaheen (D., N.H.), while Senator Pat Roberts (R., Kan.) hopes the remark will help him defeat Greg Orman.

The Washington Post’s Chris Cillizza predicted this would happen. “The Obama political team is working under the assumption that if you dislike President Obama, nothing he says or does is going to change that reality. So, why not show the Democratic base that this election is worth fighting for?” Cillizza wrote yesterday. “I think that underestimates the impact of an unpopular president (on video no less!) bluntly insisting that an election in 33 days is indeed a referendum on his policies. Republicans couldn’t have written a better script than that.”
