I'd heard it for months: Write off Kentucky, Amy McGrath is a terrible candidate. But last night, I watched the McGrath debate with Mitch McConnell, and it was freakin' wonderful. She kicked his ass up and down from one end of Kentucky to the other. (Do watch the entire debate, it will really energize you.) This debate might be what they call "a game changer." Last I heard, Amy McGrath was 15 points down (they don't poll much in Kentucky) -- but I suspect her performance last night changed a lot of minds and we should expect that spread to tighten up.
