if I were an American, I strongly support Trump's efforts to get America out of the WHO. because Covid 19, WHO and China are a conspiracy. but if this happens I am afraid other countries that do not believe in WHO will act like America did too, it will end up in chaos.
How come that "Covid 19, WHO, and China are a conspiracy"? I really don't get what you mean in this sentence.

Though, If I we're an American, I would go against trump. I can't understand the logic of threatening the WHO when all the organization wants is to investigate the current situation of the pandemic in the USA. It really smells fishy to see him getting very defensive for something he doesn't take seriously.

However if we were to assume a hypothetical scenario where he actually walks the talk and quits WHO, do you’ll think that it could have a negative effect on his votes share?, as Democratic Party will raise this topic that he walked away from WHO when Covid19 was at it’s peak, or the voters won’t care at all about this?.
I do think it will garner negative thoughts about the current administration, given that the election in the USA is just right there in the corner. The closer the election, the more he garner attention from every action, even small ones that he does. Ergo, this will give negative effects on his vote shares.
