Our old World Book encyclopedia (from 1980), IIRC, essentially said this is why socialism hadn’t really gained traction in the US. (Not in these exact words, but I think it did mention the vast frontier.) Its article on communism had a big, gloomy, B&W picture of the Kremlin. The socialism article had no picture which, in comparison, was a more neutral presentation on the part of the editors.
They did when I was still on Facebook. (Well, not everybody – it’s like how we each have millions of square millimeters of skin, although we mostly think about the square millimeter with a sliver in it)
I don’t think it really changes anyone’s mind about a particular candidate, but think it affects people’s choices about whether to vote at all.
