And here is the historical data chart

My 2¢ as someone who runs a lot of sentiment surveys…

I could be wrong, but the Dem dip feels like it could be normal survey noise. It seems to go up and down about 4 to 5% from the historical trend line. Also, progressives are kind of a bit more of a noisy respondent group. You have less old folks, less land lines, less people with the time / energy to talk to researchers.

The GOP dip though… that looks like it’s abnormal compared to the historical trend line.
