You may want to look at some actual facts. The world in general is getting much better and is likely to continue to do so. Yes there are some pockets of failure, Russia, much of the Middle East and especially Syria, any economy dependent on oil ... but the overall longterm trends are encouraging. Obama is a right of centre centrist, hardly a voice for even the moderate left. And as someone who actually has to spend a lot of time in the US and walks through all parts of the cities he visits and takes the time to talk to different people my impression is that in the progressive states relations between different cultures are making two steps forward for each step back.
