The bottommost critique of the campaign is harsh, but what I was hearing from people I talked to. Add this (from a link in the text), about the Clinton ad-buys. Money quote: "A swing of 50,000 voters from Trump to Clinton across Wisconsin, Michigan (which has still not been called, officially) and Pennsylvania would have tipped the race to Clinton. There's no guarantee that shifting pro-Clinton ads from Phoenix and Des Moines to Detroit, Milwaukee and Erie would have done the trick. But it might have."
