Topic: The World Deserves a Vote
Since there are some nations which are so powerful and in our globalized world their actions affect populations around the world in other countries, large powerful countries like the US and China should have global elections for their countries' candidates. Of course, these might not be binding, but could provide insight to nations' voters about how the rest of the world would vote. These 'for information purposes only' global elections should be held the day prior to the day that large, powerful countries hold their elections.
Again, the premise is that since we live in a globalized world where large and powerful countries affect populations on a global level, the world population's deserves a say and deserves to be heard with regards to the election candidates of large, powerful countries.
