Does ISIS normally give warnings, or this just a right before the election special?
Yeah, I hate that my mind went to the same thing, but it did. You have to wonder if maybe both sides are posing as boogeymen for their respective teams. The Lincoln Project and VA Young Dems pretended to be neo-Nazis, and now maybe the Republicans are pretending to be ISIS?
Well, you can't say it doesn't fit the Halloween season!
There's no particular reason for it to be fake, even if it is just an attempt to influence the election.
ISIS gains from Republicans in power. (As do many other hostile foreign actors.)
