It appears you are referring to a sentiment among some Democratic insiders being “nauseously optimistic” about the potential election outcome involving Kamala Harris, a prominent figure in the Democratic party. This optimism, while simultaneously causing unease (hence the term “nauseously”), suggests that these insiders are hopeful for a win, but they are also aware that unexpected developments can occur. Remember, no matter the predictions, conclusions can only be drawn after the final vote count.
