Why are polls sponsored by One America News some of Trump's best? I spoke to Gravis Marketing, their pollster, who said that OAN has only been releasing the polls Gravis sent them that turned out best for Trump. (Gravis says they have since told OAN to "cut it out.")
This is why you shouldn't trust polls that come from obviously biased media organizations (and why we don't include them in our models).
A bit of clarification here from Gravis: They say the problem was limited to one poll out of Florida from last month, and they haven't had issues anymore. Echoes this story from @pbump

If that's true, this raises a lot of Qs about why Gravis polls are all over the place, some being very pro-Trump and others weirdly pro-Biden. Could be weighting FX from a mostly-IVR frame? Either way, a good lesson in spending most of your attention on the high-quality stuff.
