Describe A Clinton 2016/Trump 2020 Voter

At the moment probably none, but a couple of possibilities I could see are

1.  Romney-Clinton voters who find Trump not as bad as feared or the Democrats nominate a more left wing candidate so the Democrat replacement is too much to stomach
2.  Wealthy suburban college educated whites in the event the Democrats nominate a Sanders type left wing Democrat.  That group hates Trump thus they could vote for Clinton, but Sanders is a bit too much to the left.  Essentially the same types in Canada who have no problem voting Liberal, but as soon as it becomes and NDP/Tory race they flip to the Tories.  Likewise the types in Britain who had no trouble voting for Tony Blair, but voted Tory last time around since Corbyn was too left wing.  Otherwise #2 only applies if the Democrats turn sharply to the left.
3.  Few traditional Democrats in areas that have swung heavily GOP after the past decade like West Virginia.  Although most have already swung over to the GOP, sometimes people who lean a certain way but have a habit of voting for a certain point need a few election cycles before they realize the party more in line with them is the other one.

Describe someone who voted for Hillary in 2016 and votes for Trump in 2020.

a 30 year old white woman who is married and has a child, who was single, 26 and childless in 2016.

Another one is a business degree student who was still in college in 2016, but now has graduated and is making the big bucks and likes Trump's tax cuts while doesn't want to see their taxes raised.  In 2016 they went Democrat since most of their friends were and who would make college more affordable was more important than tax cuts whereas in 2020 tax cuts are more important.
