Do you want to know what made Trump president? It wasn't the thousands spent on Facebook ads or the analytics.
It was the TV media that threw away all objectivity/ethics to cash in on the ratings juggernaut of Trump. They gave him almost *TWO BILLION DOLLARS* in free airtime.
Yes, the voters made him president (not the popular vote, of course, but in PA/MI/WI), but at the end of the day the media gave him so much free airtime that he was able to cruise through the primaries and then defeat a most historically terrible candidate in Hillary.
