Kentucky's only Democratic congressman is predicting Alison Lundergan Grimes will run the most aggressive campaign that Republican Sen. Mitch McConnell has seen from a challenger.
Grimes, the state's secretary of state, has kept a low profile since announcing her bid to unseat McConnell next year.
U.S. Rep. John Yarmuth said Monday that Grimes will soon take the fight to McConnell in what's shaping up as the most costly race ever in Kentucky.
McConnell, the Senate's top Republican, got in a recent dig at Grimes, saying she announced her candidacy and went into hiding.
Yarmuth says Grimes is putting together a campaign team but will come out with a hard-hitting campaign.
Yarmuth says McConnell has been "a master at controlling the narrative" of campaigns but won't be able to do so next year.
