A few days ago there was an amazing editorial in the Washington Post. You should read it. Two things I would add:
1) Washington D.C. has a non-White majority.
and
2) When Paul's spokesperson says of D.C.'s status- “Efforts to change that have failed, and until it is changed it is not only the prerogative but the duty of Congress to have jurisdiction over the Federal District,” I think it's important to ask if Paul supports state-hood for D.C.
