No, of course it doesn't mean anything about Trump victory. He won by the rules, absolutely. For the future though, those rules should change. Even Trump himself has called the Electorial College a terrible, rigged system. If his term means abolishing it for a straight proportional vote, then some good will come out of this.
Unfortunately Trump already said that as he Won he doesnt care about the System anymore.
Because well. He Won
From the Start the Joke is.
Trump cant even Claim he was Voted by Majority.
Because he actually had less Votes than Hillary Clinton.
He only got Elected because he Won more States.
In Short he had a Small Minority in alot of States. While Clinton had a fairly Big Majority but only in a Few States.
So despite Trump having less Voters. He got Elected as President....
