The anti-Alabama/anti-Mississippi is a better description, especially with historical voting patterns, but also in that VT and WV are both very white, while AL/MS are deeply polarized between whites and AAs.
Iirc, one of the "fun facts" of American elections is that despite both being states since a long long time ago, Georgia and Vermont have never voted together for a losing candidate if I am not mistaken.
Even if including winners, Georgia and Vermont have only voted together in the following elections:
1792 (Washington ran unopposed)
1804 (Jefferson reelection landslide)
1808 (Madison landslide)
1812 (Madison reelection)
1816 (Monroe landslide)
1820 (Monroe ran unopposed)
1836* (Van Buren vs several Whigs; Technically they voted for different candidates, though since both were Whigs I suppose it counts?)
1840 (William Henry Harrison)
1848 (Zachary Taylor)
1972 (Nixon reelection landslide)
1984 (Reagan reelection landslide)
1988 (HW Bush victory)
1992 (Bill Clinton elected)
So for 124 years between 1848 and 1972 GA and VT never voted for the same candidate. This streak was finally broken when Georgia flipped Republican in 1972 while Nixon won 49/50 states (GA flipped R in 1964 as well, but of course on that one VT voted Democratic). Then they voted together for the winner 3 times in a row between Reagan's landslide and Clinton's reelection. And that was it.
And like I mentioned, they never once voted together for a losing candidate; though technically they did both vote Whig in 1836, so I suppose that is a technicality.
Ironically, it is not hard to imagine GA and VT voting together for a losing candidate soon. If GA trends further Dem and ends up to the left of the US at large, it is trivial to imagine a close election where a Republican wins while GA goes Dem.
