IIRC if DC became a state, only specific federal buildings, such as the white house, scotus & the capitol buildings would remain as a territory (due to the constitution), but, because of a amendment to the us constitution giving DC the same amount of voters _(members of the electoral college)_for the president as the lowest-representation (essentially always 3), which only citizens living inside the area would be allowed to vote for, only the citizens of white house would be able to vote for 3 whole electors.
I might be incirrect, as I am not a US citizen, but I’ve seen this mentioned somewhere long ago
