Republican Minority Leader Mitch McConnell argued he's the "candidate of change" in the Kentucky Senate race, despite his three-decade career on Capitol Hill.

"If you want change, if you're unhappy with the direction of this country, the candidate of change is the guy you're looking at,” the top Senate Republican told an audience at a Chamber of Commerce lunch in Nicholasville, Ky., on Wednesday, as reported by CNN.

McConnell is running against Democratic Secretary of State Alison Lundergan Grimes in Kentucky. If other Republicans do well on Election Night, he would likely lead the new GOP majority in the Senate.

"In this country, the way you change things is at the ballot box. And so there's only one thing that can be done this year to begin to lead America in a different direction and it begins right here in Kentucky," McConnell told the audience.

McConnell has a narrow lead over Grimes in the RealClearPolitics average of polls on the race.
