My mom voted Perot (I think), Dole, Bush, Kerry, McCain, Romney & Clinton, thus finally breaking the curse of always voting for candidates who lost the popular vote (but definitely establishing a new trend of voting for the candidate who loses the presidency).
To make things weirder, she's basically a straight-ticket Dem voter for all non-presidential elections (but like many around here, votes in GOP primaries because that's where the action is).
Just call your mom anti-incumbent in Presidential Elections!
