I feel it is getting inevitable we will win with Biden/Harris. We will win North Carolina, Arizona, Colorado, Maine, and Iowa senate seats. Georgia special election is winnable too. Minus Alabama, we will have at least 52 Democrats (enough for a manchin and feinstein filibuster buffer).
South Carolina, Montana, Kansas, and Perdue are titanic dead heats within 1 point.
I am optimistic we will abolish the filibuster by winning at least one of the dead heats.
