I read RS occasionally, I can read everything even mildly interesting or relevant in a magazine in a few minutes. My Dad listens to NPR for much the same reasons... "The better to know my enemies." :-)
Right now, RS is thrashing about politically. They're trying to decide if Democrats are too conservative, or just not liberal enough. Looks like they're going to latch on to Bernie Sanders for Prez, but that still remains to be seen.
Bad news for Hillary! and Biden, I'd think. RS is more-or-less a mouthpiece for the young liberal vote that they'll need, badly.
That is their niche, like MTV used to be with rock the vote. Now the liberal indoctrination market seems to have shifted towards late night talk shows and Saturday Night Live TV audiences.
That being said, Reader's Digest was a magazine I subscribed to since 1972. They were at best apolitical leaning conservative. Now, they are just becoming another version of the usual newsstand time wasters, kind of a print version of yahoo "news". No credibility just a method to sell ads.
