McConnell challenger Amy McGrath's campaign says it raised $2.5 million in 24 hours

Amy McGrath's campaign said on Wednesday that it raised $2.5 million in its first 24 hours, after the Kentucky Democrat announced her bid to challenge Senate Majority Leader Mitch McConnell next fall, NBC reports.

Why it matters: McGrath's campaign said that was the most money ever raised during a Senate campaign's first day. This highlights how the Kentucky race is set to become a lightning rod in 2020 — as the idea of "dealing with" McConnell was a question in the first 2020 presidential debate.
