Furthermore, there is one other distinction here: Clinton, even if she got "the most votes," did not get a majority, or even close to one. Thanks mostly to Gary Johnson, who picked off a little over 3% of the vote, Clinton finished at about 47%—and considering that no one can realistically assume that all of Johnson's voters would have voted Clinton had he not been in the race, the idea that he's a spoiler is wrong; this is not a repeat of 2000, when Nader arguably deprived Gore of the majority. Clinton was never going to beat all of her opponents combined.
There is no popular vote mandate here.
