The Democratic National Committee begins airing a TV ad today in the home state of Senate Minority Leader Mitch McConnell, calling the five-term Kentucky senator "Leader No."

This is the latest salvo in a line of criticism against the Republican leader whose party is down 20 senators. In May, the DNC released a web video questioning McConnell's leadership.

The ad's announcer states: "Call Mitch McConnell. Tell him after eight years of being part of the problem, it's time to be part of the solution."

The ad will run this week on cable stations in Lexington and Louisville.
