As I type this, we're waiting to hear the World Cup announcement on the host country for 2022. The United States, Qatar and Australia are considered the three front-runners at this point. As I type, voting is going down. So how does the voting work? SBNation.com explains:
For both the 2018 and 2022 World Cups, each Executive Committee member will vote for one of the proposals. Twelve votes are required for a proposal to win. If a round of voting passes without a proposal getting that majority, the least supported bid will be eliminated and another round of voting commences. If the final round of voting ends in a tie, FIFA President Sepp Blatter will cast the deciding vote.
It's 23 voters now because one had to be removed. But the point is 12 votes is what you're looking for.
The Unites States and Australia have 5/2 odds on winning while Qatar (and the heat) stand at 4/6. Of course, we're not sure how much that really means since they haven't even completed the voting process.
