Clinton's MOV smaller than the number of Libertarian voters in states totaling more than 123 EVs:
Mexico Nuevo, Navajo, Big Sky, Pennsylvania, Northwoods (the Northern NE/Adirondacks state), Florida, Carolina, Cuyahoga (the OH rump state), Colorado, and Michigan.
Trump's two best states (as you could imagine) are Appalachia and Texarkansas.
Of the 'river states' Clinton takes Mississippi by a whisker but Trump held a commanding lead in Missouri and Ohio (the one that's the Ohio valley)
