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

Charles Booker won the Democratic nomination for Senate in Kentucky and will face Rep. Andy Barr, who was endorsed by President Donald Trump. Booker aims to replace Sen. Mitch McConnell, but faces a challenging race in a state that hasn't had a Democratic senator since 1999. The presidential endorsement is expected to play a significant role in the November contest.
