It is my opinion that this chart illustrates the real election results for POTUS. The reason why is because it expresses exactly the emotion of the voters throughout the country. It is not a poll based on the metrics of "who are you planning to vote for". This really reflects the general consensus of the overall demographics by everyone equally over a long period of time and it captures the mood of the country just prior to the election. Never at any point in time was Biden ever leading. The supporters for Trump outnumber Biden by almost 2:1. For Trump to lose this election would be impossible without a lot of voter fraud.
Nor does it include "Not Biden" voters either. This reflects a long range trend by 100's of thousands of searches, not a microcosm of fake statistics and manipulated results.
