I feel that nominating Kamala again could go either way. On the one hand, some people on the left might not be happy with Kamala getting propped up as the leader after she was hoistered in as Biden's replacement, and there's already been a discussion about if the democrats will not be nominating a woman again for a long time after Trump beat both of their picks. On the other hand, they might just be convinced that if Trump managed to make a comeback victory, Kamala can do the same since we've been using her time as VP to prove the point of why she shouldn't win, and the fact that there's only two real candidates during any given presidential election due to plurality voting means that people might just vote her if only because they don't want whoever Trump deems his successor.
