Polls, as we've discovered in 2016, are also largely fake news. To me Yang seems to be the only sane candidate on the left, and the only one who'd be able to give Trump a hard time.
This needs a citation. There was a lot of people spinning polls or making bad predictions off polls in 2016 (like every election year), but polls are not fake news. They certainly weren't proven to be fake news just because some people were surprised by the outcome.
