1. The election's not over - not to be an ass, but I think some of you don't know how the electoral system works - you're just seeing Biden with a "higher number" and assuming it's a win.
As of right now (according to Associated Press), there are 3 blue-leaning states with less than a 1% difference (Nevada, Michigan, and Wisconsin) - they grant a total of 38 electoral votes.
All of the other contested states (Alaska, Georgia, North Carolina, Pennsylvania) are leaning red with more than a 1% margin in favor of Trump.
If Trump flips just 1 of the (Biden-leaning states and keeps his current red-leaning ones), he'll win the election based on points; Biden will have to keep all 3 blue just to hit 270.
