Answer:
23rd constitutional amendment allowed citizen in washington dc to vote in presidential election
Step-by-step explanation:
As D.C is capital city or federal district not a full fledged state
But they pay fedreal taxes and are subjected to same defence obligation mean they can't have their own
army
They are denied of voting rights historically and they are represented in lower house through appointed member but without voting right and they are not represented in senate. The Twenty-third Amendment established a vote for District residents in presidential elections and it was never implemented as states never signed on that proposel.
IF we look at other capital city across the world we find that the situation of D.C is worse than delhi (india's capital) there is 3 representative in upper house and 7 in lower house with right to vote
we should follow the model of london which has strong local government it has 2 set of police london police and for the issue of greater concern scotland yard it is not necessary that policy has to be centralised
