Mother Jones is a far left magazine, and the selections of what they print typically fit their slant People don't buy Mother Jones because they want "balanced reporting'.
So it takes exceptional courage, bordering on not caring about their own existence to publish the truth that there wasn't any "Whitelash".
To deny a popular meme of the left that allows their people to feel superior as they denigrate the country in order to denigrate "Trump voters" is simply amazing!
It seems that as the left picks themselves up off the floor, they have been forced for a moment to look around and ask "what hit us"? I'm pretty sure this self teaching moment won't last very long, but it is one of the serious advantages of being blind-sided!
