No Republican presidential candidate has led in 50 years at this point. Polls are faked to raise money for dems.
It all part of the suppress the Republican turnout effort. Happens every time.
Polls are often faked by the media, too, in the interest of dollars. Election seasons are their bonanza. Candidates must pay for their advertising up front, and at full rate, so media outlets have a strong motive to keep the races looking close, so both sides keep buying and buying up until Election Day.
