Because Trump still says reasonable things once in a while that is not completely detached from reality. The bar is that low. Desperate people will believe in anything.
It’s the same reason why many people in China and Russia like Trump, because once in a while he says stuff like this (there is even a tag that says this clip was the 12th most popular video on Bilibili at one point).
That too. American politics is more like an entertainment in China haha.
