[EM] ACF grade voting

[fsimmons at pcc.edu]

Suppose the ballot limits grade options to A, C, and F, but a sizeable faction would like to award a 
grade of B to a particular candidate.  If half of them voted a grade of A and the other half a grde of C, the 
resulting grade points would be the same.  

So in elections with large electorates there is no need to have grade ballots with all five grade options. 
Those who want to award a B grade can flip a coin to decide between A and C.  Those who would like to 
award a grade of D can decide between C and F with a coin toss.  The grade averages will come out the 
same as if the higher resolution grade ballots were used.

If two or more candidates are statistically tied, the tied candidate with the greatest number of A's and 
C's should be elected.
