You cracked the lie, er the code:
A Biden lead?
There never was such a thing.
Except maybe in the Make Believe land of Fox News.
You're missing the obvious. When Bernie was still in the race, the media had to have Biden beating Trump in polls so that Bernie did not get the nomination. Now that Bernie is out, they need to pull a Robert Torricelli on Biden. You can't do that by showing Biden leading Trump. So, first, show Biden losing to Trump in the polls. Second, have Biden drop out due to health reasons, and have a food fight at the convention.
