It's probably Bush-Kerry-McCain-Obama-Clinton-Trump. Basically a voter that swings against the national trend every time. It's also a fairly incoherent voting pattern in its own right.
This is the really hard part to explain. Are they pro- or anti-war LOL? And the 2012 vote rules out personal animosity against Obama.
They're a liberal Arizonan who McCain won the vote of because of favourite son effect.
Or they don't even need to be Arizonan; they could just be a moderate centre-left Democrat who likes how McCain is a 'maverick.'
But why would someone like that vote Trump in 2020?
