Kentucky Secretary of State Alison Lundergan Grimes (D) announced Monday that she will run for reelection, ending speculation the rising Democratic star might run for governor.
"It’s been my honor to serve the people of Kentucky," Grimes wrote in a post on her Facebook page announcing her decision. "More than you can ever know, Andrew and I appreciate your love, your friendship and your support – today, in the past and in the future."
Grimes challenged now-Senate Majority Leader Mitch McConnell (R) in one of the highest-profile contests of 2014. McConnell won by about 15 percentage points.
But Grimes emerged as one of the standout fundraisers of the midterms, stirring talk that she might seek a run for Kentucky's open governor's seat in 2015.
Gov. Steve Beshear (D) is term-limited. The field to replace him already includes state Attorney General Jack Conway (D), state Agriculture Commissioner James Comer (R) and self-funding former Louisville councilman Hal Heiner (R), among others.
The filing deadline is Tuesday.
