I would remind people that the 2018 midterm elections had the highest voter turnout for any midterm election since 1912 -- a strong portent that we have no real idea what the upcoming primary electorate will look like and you should ignore conventional wisdom
Turnout for the 2016 Democratic primaries was also relatively *low* and that will almost certainly change radically in 2020, further altering the composition of the electorate in ways we do not currently comprehend
Obviously there will be no competitive GOP primary which means the Dem electorate has potential for even further growth, with many more independents and GOP voting (in states where permitted) than in 2016 or 2008
