Outran the top of the ticket in 2016, consequences 2020?

[Epaminondas]

Hello everyone,

Lurker since 2015 here, but the activity here is such that most of my queries are already answered.

My question is: what can be said about 2020 governors who won while outrunning their presidential candidate in raw numbers?

I have:
- Jim Justice in WV (+86% over Hillary)
- Phil Scott (+75% over Donald)

- Gary Herbert in UT (+47%)
- Steve Bullock in MT (+44%) [term-limited]
- Doug Burgum in ND (+20%)

- Roy Cooper in NC (+5%)
- John Carney in DE (+5%)
- Chris Sununu (+2%)
- Jay Inslee in WA (+1%) [running for prez]

Hence my 2 questions:
1) Does this all but guarantee the reelections of Burgum, Herbert, Cooper, Sununu, since governors seldom lose votes at reelection; or are they on shakier grounds than in 2016 with Trump exhaustion cutting into their base?

2) Jim Justice and Phil Scott appeared independant of the top of the ticket: aren't they due a reversion to the norm with 2020 polarisation?

Justice switched parties so he should be fine.
