Why were residents of our nation's capital denied the right to vote in national elections until passage of the twenty third amendment?

Answer 1

Residents of Washington, D.C. were denied the right to vote in national elections because the Constitution did not grant them representation in Congress or the Electoral College. D.C. was established as a federal district, intended to be neutral and separate from state influence, which resulted in its residents lacking voting rights. The Twenty-Third Amendment, ratified in 1961, addressed this issue by granting D.C. residents the right to vote in presidential elections, allowing them to participate in the democratic process.
