Yes, both sides campaigned according to the rules of the game (the electoral college) and just 55 thousand votes in PA, WI & MI tipped the election for Donald.
So Trump triumphed, but it's with a weak ass mandate ... when despised crooked Hillary soundly beats you in the popular vote by more than 1.5% lol ... hell, even Bill Clinton won a greater % of the pop vote in '92 (than Donald has) with a serious third option of Ross Perot on the ballot ... and they said Billy-boy didn't win a mandate.
