Re: How to lose
"The National polling was broadly correct. It said Clinton would win by a few points, she did."
There was a map of votes for Hillary after the election displayed as topographic. She won the largest cities and not much else. This is what the founders of the US had been afraid of, the largest cites dictating the government. Some states that were painted blue were that way due to one or two major cities dominating. A candidate that wins an overwhelming number of votes in Atlanta can win the whole state regardless of how all of the other residents vote. I can't remember if it was Georgia that was that way or another state, but there were a couple. A lot of polling is done in major cities which can mean they have very skewed results. The numbers don't have to have a bigger error bar than expected by much to be wrong about a tight race. The 2016 Presidential election was a big surprise for a lot of people.
If Joe Biden is allowed to speak much and certainly if he's allowed completely off script, he's in big trouble.
