Which governorships are pretty much unwinnable for either major party?

Not sure that Virginia is unwinnable yet for Republicans, though it is headed that way. But I can see where you're going with Colorado. The Republicans have lost four straight gubernatorial elections here in a row, and the last Republican victory was in 2002 with Bill Owens. Owens is also the only Republican Governor that Colorado has had in the last 44 years, since 1975. Given Colorado's ongoing transition into a Safe Democratic state, I don't see the drought being broken anytime soon.

Every state is winnable for both parties. If it wasn't for Larry Hogan, everyone would have Maryland on this list, but they have a Republican governor.

There is some validity to this. Wyoming, Oklahoma, Tennessee, and Arkansas all had Democratic governors as recently as 2010; only in this decade have they moved "beyond reach" for the Democrats. California and New York, likewise, had Republican governors during the last decade, and Chris Christie just left office in New Jersey a few years ago. But other states have had a much longer drought: Oregon hasn't elected a Republican governor since 1982, and South Dakota last elected a Democratic governor in 1974.
