FWIW Hitman, I think in general you are correct. While I do find some polls somewhat specious, I think you can pretty effectively use them to gauge overall trends.

Where bias is clear is in the obsession with "plummeting polls" when it's related to Republicans and absolute silence when the polls rise. The reverse appears to be true, since Clinton's "no one cares about impeachment" polls were trumpeted...but we rarely heard about it when they were falling—and if we did it was generally blamed on an electorate that wasn't paying attention.

Your added dimension is correct and wise. Thanks.
