They were duped in the sense that they are voting against their own financial interests unless they are extremely wealthy. It is not unlike slugs voting for salt, in that way.
They truly believe the poor will prosper, and those that don't are just lazy.
I was more getting at that they have duped themselves into believing they are making logical choices, which the Cunt has most certainly manipulated by specifically not hiding what he's for. As you pointed out, this can apply equally to any extreme of the political spectrum, I'm just a little more pissed off at one side than the other rn
