Remember that a good percentage of his supporters are low IQ or low educated and both at the same time.
And others like everywhere are crooks looking for ways to make money even at the expense of gullible persons health.
Pew research in 2012 (which is not that long ago) showed that Republicans are more informed than Democrats. You can see this in the section "Partisan Differences in Knowledge" in this article:
https://www.pewresearch.org/politic...al-parties/#partisan-differences-in-knowledge. Not only did "Republicans fare substantially better than Democrats on several questions in the survey," Pew says, but that's "typically the case in surveys about political knowledge." Republicans answered 12.6 of 17 questions correctly, versus 11.4 for Democrats, and Democrats only outperformed the GOP respondents on one policy question.
In addition to being more knowledgeable than Democrats, Republicans also have a higher IQ. A social scientist named Noah Carl found that Republicans have a verbal IQ 2-5 points greater than Democrats. In the abstract of his research paper he says: " ... I find that individuals who identify as Republican have slightly higher verbal intelligence than those who identify as Democrat (2–5 IQ points), and that individuals who supported the Republican Party in elections have slightly higher verbal intelligence than those who supported the Democratic Party (2 IQ points)." You can find his paper at

I also want to mention how the research also shows that social conservatives (those that oppose abortion, oppose gay rights, and oppose secularism) have a lower IQ than those who are socially liberal (those who support abortion rights, support gay rights, and support secularism). So, the religious zealots are on the dumber side of the Republican party, but they are not the whole Republican party. There are socially liberal Republicans who believe in free markets, and they are called classical liberals. And so, as Noah Carl puts it, "My findings suggest that higher intelligence among classically liberal Republicans compensates for lower intelligence among socially conservative Republicans."
I think this is all significant because it plays into important public perceptions of the respective political parties we have in the United States. Many people are disposed to vote for Democrats because it is perceived that Republicans are the stupid party. If one were to base their political beliefs on late-night shows or left-wing media sources, they would no doubt come away with the conclusion that the Republicans are the stupid party. But the reality is that Republican voters generally know more about policy and are better able to think critically through issues (assuming that verbal intelligence translates into better critical thinking). Think about that the next time you hear someone insult MAGA voters, Republican voters, Sarah Palin sympathizers, or George W. Bush sympathizers.
