Senate Minority Leader Mitch McConnell (R-Ky.) is putting his own spin on "'Twas the Night Before Christmas," using the classic holiday poem to attack his Democratic challenger Alison Lundergan Grimes in a radio ad released Monday.

McConnell narrates the ad himself, which reworks author Clement Clarke Moore's poem to criticize "liberals" over the Senate's passage of Obamacare on Christmas Eve four years ago. It also goes after President Barack Obama for his so-called "war on coal," for raising taxes and for allowing the national debt to hit record levels, before tying Grimes to the same policies.

"Twas the night before Christmas, four years ago. Liberals wanted Obamacare but Kentucky said no," McConnell says. "If you like your plan you keep it, they said with a twinkle in their eye. Newspapers now say, that was the year's biggest lie."

"The differences are stark and your choice will be clear," he adds later. "But you’ll make your decision in November next year. So Merry Christmas and Happy Holidays to Kentuckians all. Especially Alison Lundergan Grimes, I’ll see you next fall."

"As we've seen from his insurmountable disapproval ratings, Kentuckians are tired of Mitch McConnell's silly political games," said Grimes spokeswoman Charly Norton. "Our campaign looks forward to continuing to hold McConnell accountable as folks across the Commonwealth unite around Alison's campaign. The people of Kentucky are ready for a new Senator in the new year."

This isn't the first time the McConnell campaign has gotten into the holiday spirit. Last week, his campaign manager Jesse Benton sent out a fundraising email urging supporters to donate to McConnell in order to win the "War on Christmas."
