Hillary/Moore voters?

[Nichlemn]

My guess is that the majority of people with such "incomprehensible" votes are low information voters with incoherent political views. They're the kinds of people who don't know the name of the Vice President or what party controls Congress, or call themselves "very conservative" but support single-payer healthcare. Most don't vote or pick a "team" to stick with, but a handful probably do vote what seems to be almost randomly.
