Calling her party's victory in the Kentucky governor's race a jolt of momentum for her own bid to unseat a Republican incumbent, Democrat Amy McGrath has officially filed to challenge Senate Majority Leader Mitch McConnell in what looms as a bruising, big-spending campaign next year.

McGrath, a retired Marine combat pilot, touted many of the same issues -- health care and good-paying jobs -- that Andy Beshear highlighted in ousting Republican incumbent Matt Bevin in the November 2019 election for governor. She is one of 13 candidates from both parties looking to take McConnell's seat.

Other Democrats to have filed are Andrew J. Maynard, Eric Rothmuller, John R. Sharpensteen, Jimmy C. Ausbrooks and Mike Broihier. State Rep. Charles Booker, D-Louisville, also announced on Sunday that he intends to file for the seat.

As the most powerful Republican in Congress, McConnell enters the race as a strong favorite in his pursuit of a seventh Senate term in 2020.

The Republican senator touts his leadership position and his ability to deliver federal money for the Bluegrass State.

Other Republicans to file are Wendell K. Crow, Paul John Frangedakis, Louis Grider, C. Wesley Morgan and Nicholas Alsager.

Elsewhere, 1st District Congressman James Comer, a Republican, has filed to seek another term. At press time, no other candidates had filed for the post. He represents all of far western Kentucky and a south-central portion of the state.

For the 4th District House seat in Frankfort, incumbent Republican Lynn Bechler will seek election to a fifth term to represent Caldwell, Crittenden, Livingston and a portion of Christian County. No one else had filed for the seat at press time.

Sen. Robby Mills will continue to represent the 4th Senate District and Caldwell County, as his seat is not up for re-election until 2022.

Five Democrats have filed for President, Pete Buttigeig, Tom Steyer, Andrew Yang, Joe Biden and Elizabeth Warren.

The filing deadline for Kentucky's May primary is Jan. 28.
