This is another logical fallacy https://en.wikipedia.org/wiki/Argumentum_ad_populum
> All you need to do is read his tweets to see that he should have less power (much less), not more
I'd like you to make a real argument. What specific tweet of his implies he should have less power and why?
That wasn't a claim, it was a hypothetical.
> I do not think people want guys like this in power: https://xcancel.com/tobi/status/2081155797640171641
What is it specifically about this tweet that means him being in power would have bad outcomes?
I don't see him making that suggestion. It's pithy so it's hard to really pin down a meaning to the tweet but I think he's saying that these town sessions aren't a meaningful expression of democracy because only a specific section of society is in attendance and one that may not understand key issues relevant to working or young people.
He clearly isn't calling the other categories he listed (the " Retired, Unemployed, Unemployable") useful idiots, that's why he listed "useful idiots" separately. I don't know to whom he is referring as useful idiots but I don't think it's immoral in itself to use the term "useful idiot."
