Very thin margin of winning

Last night in Iowa, Mitt Romney officially edged Rick Santorum by eight votes. There were 122,255 ballots cast. If our math is right (and feel free to check us), the difference comes to about 0.00654 percent of all votes

By now everyone who follows American politics would have heard that Mitt Romney won Iowa Caucuses by 8 votes.  Out of hundred of thousands of ballots casted, margin of 8 votes come out to be less than 0.01% of all votes.  Talk about a thin margin, it could not have been any more slimmer margin than this (only 7 other even slimmer margins are possible!).
