Keep in mind that if popular vote mattered in their system, the election results would have been different; the campaigning would have been different; the candidates might have even been different.  All the postulating and hypotheticals are beyond meaningless and are the hallmark of bruised egos and sore losers.  

Case in point: Canada's last two federal elections.  Harper won a "Majority" in 2011 with 39.6% of the popular vote and cries abounded about electoral reform and how a majority gov could be formed with a minority of voters was proof of a failed democracy.  Fast forward 4 years and Trudeau won a "Majority" in 2015 with 39.4% of the popular vote... those exact same people who cried about a flawed system were (are) now claiming that such a result is proof of a "strong mandate" and revel in their win.  Funny how those on the Left are able to change their tune so flawlessly based on the exact same data.  I believe that is called hypocrisy.
