The GOP has a deep distrust of the media and distrust in the political process.
Trump is a serial liar and his tweets are often inflammatory.
The Republican Party is also prone to authoritarianism.
For a party with such a large contingent of the population, there’s little room for any sort of internal democracy or meaningful governance.
It’s not just the media, either.
The Republican Party has been accused of authoritarianism at every level, including by members of its own party.
Even when it comes to the media itself, the GOP is more authoritarian than the GOP itself.
When you’ve got the Republican Party controlling both houses of Congress and the presidency, you’ve just got a lot of authoritarian tendencies.
