CNN took care of that by taking their poll from a 15 point Biden lead to a 4 pt lead and only ONE point in battleground states. Made sure dates of poll were from before COMMIE-la announcement.
Now they can take it right back up to 15 points next week and show a DOUBLE DIGIT bounce from COMMIE-la VP and Convention.
QED
I think you nailed it!
They only do polls as part of the narrative.
