Bluegrass Democrats make their choice to replace McConnell, take on Trump-backed Barr

Bluegrass State Democrats chose their challenger and hopeful successor to longtime Sen. Mitch McConnell, R-Ky., on Tuesday night.

Charles Booker, a progressive former state representative who has squared off with Sen. Rand Paul, R-Ky., in the past, clinched the Democratic nomination for Senate in Kentucky, besting a crowded field of seven candidates. 

Booker will now face Rep. Andy Barr, R-Ky., who similarly dispatched a deep field of candidates, but was heavily spurred by a late endorsement from President Donald Trump.
