Are libs of US that naive/insane to blindly follow him? I observed that good number democrats(supporter’s) acknowledge that Kamala is not the perfect solution. Are libs truly that naive/insane?

Completly out of context, but I want to ask an important question

I am from India, currently studying in Australia and back home I was actively involved in politics. Being involved in politics means I have to give a damn about the US, and for the first time in my life I happened to watch the presidental debate. Ever since, I have been wondering how Trump has so much following and how was he a president of your country? Not a single statement of his made sense, and not to mention how he always deviated from the topic being discussed. Can someone please explain what is happening in the US?

Its been a long time since I came acorss such a calm and composed discussion, this is just an appreciation comment. I do not have anything valid to add to this conversation
