Don't let schadenfreude and tribalism blind you for the reasons for disliking this person. You don't win in politics if your opponent dies from old age, you win by shifting the forces that decide elections. Cheering on the... lets see here... inescapable march of time on a human's body invites much the same onto yourself in the future. That is, don't laugh at old people deteriorating if you don't want younguns in the future to laugh at you or your grandma. It's a journey that we all take, and I feel like it should have some dignity in it.
I wish he and his family good health, and that the political structure around him fades into history.
