Mitch agrees to debate Grimes, and to do it on public television

Knock me over with a feather. Are Mitch's internal polls showing more vulnerability than external ones?  Or at four points up is he now confident that a debate will be the finishing blow?

Jack Brammer at the Herald:

Kentucky voters will get at least one chance to see U.S. Senate Minority Leader Mitch McConnell and his Democratic opponent, Kentucky Secretary of State Alison Lundergan Grimes, debate the issues on statewide television.

Shae Hopkins, executive director of the Kentucky Educational Television network, announced Monday that McConnell's re-election campaign had accepted its invitation to debate Grimes at 8 p.m. Oct. 13 on Kentucky Tonight. Grimes accepted the invitation in June.
