Once again a hypothetical scenario about Obama being in the office where the whole purpose is to make Trump look bad. Yes, he does have way more influence than anybody else, he also got selected as the president of USA and might get re-elected again, so there must be atleast something that he does well. I don't know American politics that well that i'd be able to say what he has done or what he didn't do, but if i built my personal image about him what's being said in the internet, he would have never made it to the president in the first place and even less, for having a possibility to get re-elected.
Some of the people think about this Corona situation that it should be dealt with by letting it be, then there's others who won't leave their houses etc. Everyone have different way of approaching this, whatever you will do as the leader of the country, it will always lead to the fact that certain group ain't happy. If everyone agreed on everything 100%, there wouldn't be any reason to have single person being in the charge of any country and people just could go on, agreeing on everything and everyone would be happy. Too bad it will never be like that, decisions will be made, whether you agree with them or not.
