Barring something remarkable in the national political events, the events that surround them, or external events, if the candidates are expecting big bounces from their respective conventions, I strongly suspect they’ll be disappointed.
Convention “bounces”, frequently short-lived improvements in approval ratings, are largely a thing of the past and have been since the advent of 24 hour news coverage and social media. There will be no 16 point swings in opinion for either candidate (given the provisos in my first sentence).
