Now this is a great ad from Jack Conway, taking Rand Paul to task for having said a "the real answer to Medicare would be a $2,000 deductible":

Voice Over: More from Rand Paul Rand Paul: The real answer to Medicare would be a $2,000 deductible. KY Senior 1: A $2,000 deductible? KY Senior 2: Rand Paul wants us to pay $2,000 just to get Medicare? KY Senior 3: That’s crazy. KY Senior 4: I can’t afford that. Rand Paul: The real answer to Medicare would be a $2,000 deductible. KY Senior 1: I don’t know what planet he’s from. KY Senior 5: Rand Paul is off the wall with a $2,000 deductible. KY Senior 6: Doesn’t he know that we can’t afford that. KY Senior 3: The more we learn about Rand Paul, the worse it gets. Attorney General Jack Conway: I'm Jack Conway. I approve this message.

This ad works because it is credible, entertaining, and important. It's credible because it uses Rand Paul's own words; it's important because raising the Medicare deductible to $2,000 would be a serious burden on seniors; and it's entertaining because instead of a traditional voice over, you get to hear from actual Kentuckians responding to Paul's extreme proposal, and they do so with a biting sense of humor.

The ad also works strategically because older voters tend to vote more heavily in midterm elections and Rand Paul has had loose lips when it comes to his plans to raise Medicare costs for seniors. Just last week, for example, he said seniors need to "bear more of the burden." So this is an issue that impacts likely voters and it's not going away anytime soon.

With Conway and Paul in a dead-heat, Kentucky is very much in play.
