This feels like a realistic result; albeit disappointing. One would expect a poll like this if this is a narrow cruz win by 4/5 points to balance out the Cruz+1/2/3 polls.
Regardless, Atlas will now treat this result as the new standard and act as if the dynamics of the race have changed. Until we get a Cruz+2 poll by literally any pollster at which point everyone will act like it's a horse-race again.
A subdued version of the Arizona Senate race?
I'm just surprised it took until mid-September to get to this point
