LOUISVILLE, Ky. (AP) — Voting on Tuesday appeared to be running smoother than primaries held two weeks earlier in Georgia and Nevada. There were no long lines in Kentucky or New York like the ones seen in Milwaukee and Atlanta. On Tuesday, there’s a lot of interest in two contests in particular. One involves former Marine combat pilot Amy McGrath’s fight for the Democratic nomination to challenge Senate Majority Leader Mitch McConnell this November. The other involves House Foreign Affairs Committee Chairman Eliot Engel of New York. The Democrat is seeking a 17th House term. McGrath and Engel are facing African American challengers fueled by voter fury over racism and recent police killings of Black people.
