The current AI for selecting the host of the world congress is too simplistic; civs that don't have nearly enough votes should not be voting for themselves. As it stands, since the human player is the only player who will ever vote for another player, it's extremely easy to make sure that someone with similar goals or who is sympathetic to you will become the host of the congress every single time. The AI should be changed so that players with less than half of the votes of the vote leader will vote for players who they like or who have proposed measures they like for the next vote.
