After looking at the lists of all of the people who've voted so far in both votes, I've gathered that:
1. A majority of the people who voted for Japan in the first vote didn't vote in the runoff,
2. The people who voted for Japan in the first vote who did vote in the runoff all voted for China,
3. Almost everyone who voted in the runoff stayed with their original choices (except for the Japan voters, because Japan isn't in the runoff,)
4. A large number of people who voted for Russia in the first vote have not voted in the runoff yet,
5. A majority of people who voted for China in the first vote have already voted in the runoff so far,
6. And most new voters in the runoff (those who didn't vote in the first vote) voted for Russia.
