His opponents have to give a name to their enemy. If they can make it seem as if he is someone to be ridiculed, or feared, or that can cause a person embarrassment by being associated with him, then that is what they will do.
His opponents know that attacking him on policy is not going to be effective, because the comparison with the incumbent does them few, if any, favours. So they go after his character, where they know there is more chance of success. Calling him Supreme Leader sounds a lot like calling him a dictator (but the idea of having Rocky and Bullwinkle taking him on is flat-out hilarious). The irony is that the incumbent is operating far more like a dictator, although in his case more of a puppet figurehead controlled by a shadow politburo.
The media have an important part to play in bringing the narrative to life. Rather like the Russia Collusion hoax, which, although fake a hell, has embedded itself in the psyche of many liberals, leftists and loonies, the more it is said, the more it is believed, much along the lines of the Nazi Big Lie. Apart from a few outlets, most media in the country leans left to a degree, some a little, some a lot. If they can control the message, the can control the electorate is the belief.
What disturbs them most is that America appears to be waking up. Despite the outwardly positive economic signs, there is the underlying knowledge that the economy sucks, unfettered immigration is a ticking timebomb, America’s global standing is appearing weaker by the day and the incumbent is a doddering, incompetent, corrupt old man that they need to protect and preserve at all costs.
Because the alternative is a second term for Donald Trump. This time he knows what he’s up against and what he needs to do to the entrenched careerists in Washington and the Alphabet Gang to ensure that his second term does not resemble his first.
And that terrifies them.
