For people who don't get OP, he's kind of got a point. If party registration of DC is around 90% D, 5% R and 5% I, and Trump has 95% support of Rs but Biden only 80% support of Ds, than Biden at 93% of the vote in DC would be unrealistic. It would be more like 74.75% D to 25.25% R (assuming Indies break 50/50). Of course, there's also the strong possibility that party registration in DC is meaningless because whether you're R or D, you're probably swamp and hate Trump.
