None so blind as those who will not see.

A rolling poll will not change its methodology as it would invalidate the poll for at least a few days. It would be difficult to do and pointless as well.

Results are changing because of unforced errors by Trump.

I can't remember if it was 2008 or 2012, but the rolling Rasmussen poll changed it's demographic model midstream. It was noticed on FR first as many people were carefully tracking its day to day polling. No one could figure out what happened. Then a few days later, Rasmussen issued a statement explaining they had adjusted their model. So, it does happen.

If that didn't happen in this case, and a seven day rolling average shows the very significant change reflected in the last two days of this poll, than we should expect to see even more wild shifts in all the other polls out there. We'll know in about 7 days.
