Different polls even if on the same day or within a couple of days can give entirely different numbers. This is why I stated I wish RCP would be running an average on impeachment like they do with Trump's job approval. On that the polls range between 40-49%, but RCP averages all the recent polls together which I think gives us a more accurate number. Every once in awhile you do get a skewed poll.

The kind of poll is also important, if one is using it to gauge elections. You have all adults, but we know 45% of them don't vote. Then we have polls who do registered voters which history shows around 65% of them do vote. Finally are the likely voter polls which around 80% of them vote. Then there is the margin of error in each poll which outside of a very few actually pay attention to.

You probably know all of that. YouGov did registered voters with a margin of error of plus or minus 2.9%. I don't have the faintest idea which poll PBS used. I haven't watched PBS since they took Dr. Who off the air some 25 or so years ago.

It's high past time that we start electing Americans to congress and the presidency who put America first instead of their political party. For way too long we have been electing Republicans and Democrats who happen to be Americans instead of Americans who happen to be Republicans and Democrats.
