It works because they’re fucking weird! There’s normal people who are Republican voters but the Republican Party is basically all weird people. If a motherfucker dresses like he’s in a barbershop quartet in high school or college, you know damn good and well what party they’re going to support (musical theater kids excluded, obviously). It’s not normal to call in the genital inspector and demand to see a youth sports participant’s crotch because they whooped your daughter in U-11 soccer. Ted Cruz is a Republican and he’s the weirdest person on Earth.

And that’s doubly true nowadays where you have to know extended lore from the Fox News extended universe to know what the fuck they’re even talking about.

Edit: And who the fuck makes Christmas cards where their whole family is holding guns? Plenty people treasure the second amendment and send normal fucking Christmas cards.
