Some Americans don't seem to be able to differentiate between socialism and communism. I think it's because both sides are more to the right of politics than we are here.
RE Brexit, YouGov has asked the same question for the last 4 years:-
"Was Britain right or wrong to vote to leave the EU?"
The most recent vote, on 7th September, was Wrong 47%, Right 41%, Don't know 13%. Since 31st August 2017, the answer "Wrong" has consistently had the higher percentage vote. So for over 3 years the government has been bumbling down a road, it seems, Britain has decided it doesn't want to travel.
Trump may be voted out with any luck. We're stuck with the madness that is Brexit. What a crazy world we live in!
