This "Russia hacked the election" meme seems to be dying down, since apparently they didn't, and since Trump doesn't seem to be leaning especially pro-Russian.
People just seemed to leap at this meme, which never had a lot of evidence. It recalls the pragmatic theory of truth, which is that truth is that which works, often understood to mean that truth is whatever works right now, tomorrow be damned.
The trouble is,
Tomorrow will come,
And made-up truths
Will look kind of dumb.
