They all said the same thing last time. They have to say Biden is leading, they have no other choice. It's the set-up for rejecting the results and accusing the Trump side of cheating.
Just look at the verifiable optics: compare rally turnouts Trump v. Biden, look at shitty ratings for Dem supporting media like pro sports, Hollywood, MSM networks, etc…, etc…Also use common sense. Most people know what Biden/the Dems represent, and most people don't want that.
If Biden won, would there still be "unrest"? I seriously haven't heard why the need for the rioting after the election. I always assumed it was because they thought Trump was going to win, which flies in the face of what they're telling everyone about Biden being in the lead.
