If Trump continues to stay unacceptable to Atlanta Republicans, and bleeds 10% support to Johnson (if not her), she might need only 25%.
If Johnson got 6, the scenario for Hillary to win is this:
95% of African Americans (30% of the electorate)
70% of Hispanics/other (5% of the electorate)
24% of whites (65% of the electorate)
This would give Clinton 47.6%. Add Johnson's 6% and Clinton has a 1% win since there is only 46% of the vote remaining to be had. Now if Johnson's 6% falls to 4%, Clinton would need 25% of the white vote to win with 48.25%, or a 0.5% margin
