Democrats and the media are willing to railroad the President, and anyone who would railroad another person wouldn't think twice about selling their own country out.
The media and Democrats have been calling President Trump illegitimate. They are pushing the illegitimate narrative for three reasons. First, they want to defame the President. Second, they want to cast doubt on the legitimacy of the 2016 election to prop up their failed Russian meddling/collusion/interference scam. Third, and most important, they want to cast doubt on the President's loyalty to America to cover up their own treachery.
