Unfortunately, there are too many idiots out there who have already made up their minds and will still stubbornly vote for him regardless of whatever they hear about him next.
or against him with no less blind zeal
While that might sadly be true, to some extent, those words have also been used as
whataboutism that serves no other purpose than to sow more discord and polarisation. It is not a valid argument for or against any side.
It is absolutely clear, from any objective viewpoint that Trump and his PR machine consist of despicable human beings. His ego does not allow him to take a step back, admit wrong-doing and repent. Instead he and his entourage is spewing more lies, accusations back against critics so as to create more confusion about what is the correct narrative (or to make Trump look "average" in a weird twisted comparison).
This is a downward-turning spiral that is tearing the US apart!
From what I have seen, people who speak out against him tend do to be more educated and open-minded, with stronger moral fibre. People are speaking from knowledge, not from blindness.
Everyone with half a mind who had held any attention should have figured out long before the previous election that he was a total ****head, a reckless jackass and without any merits to have the job in the first place.
The argument you are relaying would perhaps have
some merit if there was
any recent indication that he was about to repent and change himself, but there hasn't been
anything of that nature. I dare you to come up with anything - and I am ready to shoot that down with facts.
