I'd have to go back through the other threads to find out. I kept track of the votes for the first time last year, and the largest margin of victory was Enhance over Bye Bye Big XII. Both were elected as LBs (along with Minnesota_Husker) but Enhance had 13 more votes than BBBXII (27-14).
Last year Crewe won Offensive Coordinator over EZ-E by one vote, with 52 total votes cast. The most votes cast last year for a single-position vote (as in, not for RB, for which you vote twice, or WR, for which you vote three times) was 56, for the Head Coach position (which EZ won).
Crewe having about 60% of the vote is probably a record. Most votes are pretty close.
