Because they’ve been claiming 100% of the ballots were in with Trump having a sizable lead but they keep finding ballots and reducing his lead. It’s called “ballot harvesting”.
I had no idea about this until someone pointed it out to me today, I couldn’t believe it. How can they claim 100% and still accept ballots? Like on this link, see where it says “100% reporting”? It’s been saying 100% reporting all day yet his lead shrinks and shrinks and no doubt Biden will pass him. Why? Because they are cheating...

Could be the 100% represents in-person precincts and what they're counting now is absentee & provisional ballots.
