Many of us were screaming about this in 2016. Obama said it perfectly: you have to show up, because just showing your face in a red county can be the difference between losing by 15 points and losing by 30 points. Hillary didn't show up anywhere, and ended up losing multiple counties by 30-40+ points across the nation. You can't win like that.
I love this train tour. It's perfectly timed too. While he's touring around white areas trying to get folks on his side, Kamala will be the main attraction during the debate next week - exciting black voters.
