If Saccone gets “53, 58 and 57%” will that cover a Lamb lead of 579?
Excluding the military (and provisional) votes, if there are 3,204 outstanding votes in the 3 non Alleghany counties, those percentages will not be enough. To make up the 579 difference you need to make up 579/3204 = 18.07%. This translates to 59.04%. (You may need to bump this up slightly for the Libertarian vote.)
