Interesting. If 2018/2022 WC's go back to a vote with the original bids considered only , one would imagine the least corrupt bids would come out on top however, I suspect the two runners up would get the gigs. Portuagal/Spain 2018 & USA 2022.

Would that be fair though because it could easily be argued that the fraudulent votes that went to Qatar might have gone to the bid that finished 3rd elevating them above the US! Complete re-run would be better. The fact that Russia has 2018 would pretty much rule us out.
