I’m worried too but polls aren’t everything and aren’t always right. Trump is leading Biden within the margin of error in virtually every poll. Democrats have generally been outperforming polls for the past few years. Trump has been campaigning non-stop for almost 10 years, who can else beat him at this point, but the Democrat who actually beat him four years ago, and who won the Democratic primary? When Megadonors and establishment types create buzz about dropping Biden for the corporate media, it leads to uncertainty and damages his poll numbers as well.
Biden has moved left and is the most progressive President we’ve had in decades. If you notice it’s only the center-right establishment of the Democratic party that wants him out. Stein is on Putin’s payroll as much as Trump, and West is irrelevant.
