Ironically, Idiocracy was too optimistic. The "idiots" of the future still ultimately respected knowledge and facts. They made the main character president once he clearly demonstrated he was the best person for the job.
In real life they'd just say the "big government deep state" is spreading "fake news" about Brawndo.
Well, the US does currently have a president who got (at least partly) famous in the Pro Wrestling circuit, so big points there. But it's only a superficial resemblance.
President Comacho saw a real problem (lack of food), realized he needed help tacking the issue, sought out literally the smartest person in the world, followed his advice and solved the issue.
President Trump makes up problems, staffs his cabinet with some of the lowest quality members those offices have ever had, discards virtually all expert advice (In his own words, he only consults himself because he has a "very good brain") and generally seems to exist solely to troll people.
So even though Idiocracy seems to have hit it right on, it didn't. Mike Judge still could not make the mental leap required to make Comacho different from what he already knew (and I don't blame him).
I would add that Idiocracy's theme was the dumbing down of society, but in spite of society's failings the democratic government continued functioning well in working on the citizen's best interests. Unfortunatly Trump's government appears to be doing the exact opposite, to the point of looking as a government ran by anarchists trying to undermine it from within. That's arguably far worse than Idiocracy's central theme.
The current administration, the one you called Idiocracy, stood up against dictatorship China and exposed the bubble mirage that was the Chinese economy. The Chinese economy is now crashing hard. This current administration did what many said was impossible: wage increases in the age of automation and globalization. This administration has US economy growing at 3%, when most other global economies are going into recession. This administration gave jobs and money back to the main street people, when corporations were eager to give those to the prison labors in China.
You might be reading/watching the mainstream media too much.
