> Yang campaign is actually seeing exponential growth. In what? His polling position has been bouncing around within the margin of error with no progress for months. Yang's got some good ideas, and he's certainly one of the most interesting candidates of the cycle. But he's got no momentum.
Yang is polling at 8% nationally now. That's more than margin of error.
Yes, there's now been published a single poll which has him outside the MoE of zero. (Not outside the MoE of his polling average for any month since October, though, and statistically you'd expect with the number of polls at least one with him at 8% if he was just hovering at 3.5% for this long.)
While that's a landmark, I guess, it's a thin reed to ground a conclusion of any, much less rapid or exponential, progress.
