So the mayor is actually powerless and so too are the citizens that live there? Do you think a state can constitutionally decide that its citizens may not own guns?Actually it applies to the citizens of the country.
Did you miss the DC gun ruling?
Washington DC is FEDERAL property run exclusively BY the Federal Government, You may want to check where DC gets its money from. The 10 mile square of land that is DC is FEDERAL. It is IN the Constitution.
I have little problem with incorporation of the US Constitution on the States as long as the FEDERAL Constitution is not ignored when it suits politicians and ALL of the Constitution applies.
I have a serious problem with the fact only part of the Constitution is actually considered incorporated. Those portions the Fed does not want to apply they just ignore. And sheep like you let them. Until the 14th Amendment though the States were not covered by the Federal Constitution and the 14th is the sole reason the Fed claims it applies to States now.
I suspect the creators of the 14th did not intend for that to be the case.
