The media keeps reporting this for 2 reasons:
1) Massive voter fraud on behalf of the DNC. Big poll numbers are required to prep your minds to THINK that Biden has support, so when on Election Day they count the votes and Biden gets millions of votes, people don't think anything of it. If they reported the real numbers in the polls and Trump is ahead 80-20 then on election day it's almost 50-50, you KNOW something is up. Fake polls support a fraudulent election.
2) To give the Left hope and make them believe that Trump won by "Russia Collusion" or some such BS again and to create a climate of chaos and violence - to instigate a Civil War.
THEY want civil war.
Albert Pike predicted 2 American Civil Wars and 3 World Wars - well he didn't exactly "predict" them, he along with the Elites of the day PLANNED them, and his plan has been followed through with.

Yes, the LEFT want Trump to win. They are throwing the election on purpose - so that the communist retards go wild and start a second civil war.
