Polls suggest McConnell could be vulnerable. One name that has surfaced as a potential Democratic contender is actress Ashley Judd. Last week, the GOP group American Crossroads attacked Judd in Web ad that served as a warning about how Republicans would go after her if she runs.
Paul, who has signaled support for McConnell, said that the ad should not be interpreted as a sign that McConnell is in trouble or looks weak.
"Part of politics is making sure people know about who you are running against," Paul said. "Ashley Judd's a famous actress, she's an attractive woman, and presents herself well, and from what I understand, is articulate. But the thing is, she doesn't really represent Kentucky.”
