Loved his piece on COVID. Biden also came off as very sincere in his speech. His economic plan sounds pretty good as well. Would have to take a deeper dive into it, but on the surface it sounds good. The Segway from American youth voices to Kamala Harris didn't make too much sense considering she spent a good portion of her youth in Canada. The dictatorship part was nice, little jab at Trump without mentioning his name (kudos Joe). His part on Racism was well said. It's hard to ignore the fact that he's buddies with Robert Byrd who was a chapter leader of the KKK, but voted in favour of the 1968 civil rights act (https://www.usatoday.com/story/news/factcheck/2020/06/14/fact-check-biden-isnt-kkk-grand-wizard-photo/3183887001/). Biden had an extremely strong ending.
Overall it was a really good speech and I'm confident he can lead the USA. Good job Biden!
