Sessions vs Clinton would be a Democratic 49 state win,...and like McGovern he'd probably lose his home state by a narrow margin.
Only Mississippi would vote for him.
He'd get Goldwater results against O'Malley or Biden.
And with Bernie Sanders, he'd get a flip of the 1928 election,except instead of Massachusetts and Rhode Island,he'd probably just barely get Utah and Idaho
Mississippi has a much higher percentage of African Americans, and Mississippi is consistently 4-5 percentage points more Democratic than Alabama, so if anything, he'd lose Mississippi first.
Also the only candidate Hillary could possibly win against in Alabama is Cruz, yet he is pretty much tied with Hillary in Mississippi, meaning that he's most likely a few points ahead of her in Alabama.
