Kentucky's primary race between Democratic candidates remains too close to call
The Kentucky primary race between Democratic candidates to decide who takes on Senate Majority Leader Mitch McConnell in November is too close to call, NBC News projected. Amy McGrath, a retired Marine lieutenant colonel, had a slight edge in a tougher-than-expected challenge from state Rep. Charles Booker. Those votes include only ones cast at the polls Tuesday; none of the mail-in ballots have been counted yet. Meanwhile, Alexandria Ocasio-Cortez wins her New York primary.
