I don't believe polls are changing right now. I believe these fake pollsters are slowly adjusting their fake polls before election day rolls around so they are not charged with election rigging.
They will do it a little at a time before the cuttoff for polling happens. Slow at first so early voters cast their vote for Harris before they find out she has zero chance
