Your math is right for Bernalillo County, but in the other counties there are over 4,500 additional ballots being examined for counting.
Well, ok let's do that.
There are 8273 votes to overcome.
We know that for every 3 ballots they are keeping, they are tossing 4. Two thousand times 3 divided by 7 equals 857 votes. So best case from Bernallilo is 5857 - assuming JF'nK does really well.
Now do the math on your 4500 remaining. After separating the wheat from the chaff, we get 4500 x 3 / 7 = 1929 (rounding up to the nearest whole).
Tell me if I'm wrong, but isn't 7786 (5857+1929) still less than 8273?
