It doesn't. You really think over 90% of US media is owned by the government or threatened with closure if they don't advance pro-government points? LOL yeah sure, every country has the same problems at the same level of severity, blah blah. BS. Obama gets torn apart by a significant chunk of the media when he's President, Trump gets torn apart by an even larger chunk when he's President. If the government controlled the media the way they do in Russia, 95% of media channels would just praise the genius of the President. They don't. Media is partisan in the US; it's pro-government when that suits the partisan agenda of their base. It's not loyal to the US government.
And find me evidence of ballot-stuffing. Good luck.
