It's a Mother Jones article, of course it's garbage. Someone from the DnC probably called them up and said weare seeing less concern and panic then we'd like in advance if the midterns, let's try and get the base riledupsome more.
So this article appears to fill that request. It's just propaganda - and bad propaganda at that. There is zero evidence to back up the claims made.
It's pretty subjective content, not like you can say definitively specials do or don't show what'll happen in the midterms.
Besides I find Mother Jones pretty reputable most of the time.
