District X has 10 seats, 4 of which are occupied by Rs, 6 Ds.
The 4 R seats could be retained and the 6 D seats could also be retained.
Assuming equal distribution of population across district, this could be anywhere from 60-40 Biden to something crazy like 70-80% Biden (if the Rs barely won, and the Ds landslided).
This one is a trap, I think.
Imagine it is District X.

The 4 R seats could be retained and the 6 D seats could also be retained.
