Which blue state Republican gubernatorial seats can the GOP keep?

[Suburbia]

Which blue state Republican gubernatorial seats can the GOP keep in the 2017-2018 gubernatorial election cycle? Chris Christie (NJ)'s seat is likely to go to a Democrat, Phil Murphy, but next year in 2018, Bruce Rauner (IL) and Larry Hogan (MD) are seen as likely vulnerable blue-state Republican governors. Charlie Baker (MA) and Phil Scott (VT) are seen as less vulnerable. Chris Sununu (NH) and term-limited Paul LePage (ME) are likely to see their governorship races as tossups.

I'll add term-limited governors Brian Sandoval (NV) and Susana Martinez (NM), despite the fact that I think that NV is still a swing state and can be won by a right Republican.
