How could Trump approval drop from 52% to 46% in one day on Rasmussen? The approval is based on a three-day average of 500 polled each day or 1500 total.
My calculations show that Trump had approximately 50% of the 500 polled on Sept. 25, but just 32% of the 500 polled on Sept. 28. The 6% decline in one day is unprecedented. Daily change in approval is generally 0-2%.
Possible explanations for the sharp decline: Consider these current events: 1) Supreme Court nominee Barrett named, 2) NY Times misleading report on Trump’s Tax Returns (did not mention legitimate tax write-offs and no Russian connection- a nothing-burger).
Note: Trump was nominated for the Nobel Peace Prize for the third time but the media never reported it.
The margin of error for N=1500 is 2.5%. It is 4.4% for N=500
