He didn’t have the platform in 2016 that he has now. And he has a lot more people supporting him now than 3 years ago.
Remember how everyone believed Hillary would win? The press, the polls, the 'elites', local news, every newspaper etc etc etc... then Trump won. We don't believe in the 'integrity' of the press either - besides Trump can smell out liberal lies - and he knows how to deal with them.
This isn't much of an issue..
