I found this spreadsheet online
I don't know if this is accurate or not, but I notice that there are 13 states considered swing states. Only one of these states, Iowa, shows a clear majority of the votes for either candidate. Otherwise, no one has a majority. Whoever won those states, won with a plurality. In the non-swing states, very few show the winner with only a plurality. Those are: New Mexico, Utah, Virginia,
In fact, in those states where no one has a majority, we don't know who the majority of the voters would have voted for in a race that only included Clinton and Trump.
This is a problem with plurality take all elections. You can get a winner, who is not supported by the a majority of the voters.
When I lived in France, in 1976, I was impressed that they had two rounds of voting. After the first round, no one had a majority. Then they had a runoff election between the two lead candidates, so they could determine who would really get the majority.
I have a long standing concern about this, because Hitler was elected with a plurality. A majority of Germans never voted for him.
Glad to see Maine adopting ranked voting
This is one way of dealing with a situation where no candidate has a majority.
