To exercise exclusive Legislation in all Cases whatsoever,

over such District, (not exceeding 10 Miles square), as may by Cession of particular States, and the Acceptance by Congress, become the Seat of the Government of the United States… 

US Constitution Article I Section 8.

This was an issue back in 1789.  The one lucky state that got the federal capital in its territory, Philadelphia, or Boston or Baltimore or even New York, would gain humongous influence over federal policy and lawmaking.  And benefit from federal tax money getting spent in their state and hotel bills paid by all the federal lobbyists.   To prevent an unseemly squabble and endless bad feelings, and not jeopardize acceptance of the Constitution by having such a clear fighting point in it, the Founders decided to create a new green field federal capital city, not to be part of any existing state, location to be specified later (TBSL). 

Now, in 2020 we have a bunch of DC people whining that they don’t get any votes in Congress.  I don’t feel sorry for them.  The river of federal money pours into DC and gives the city a subway, best museums on the planet, Secret Service and FBI and who knows what else for law enforcement, good paying federal jobs that will not quit, Navy Yards, and the home office of every federal agency that ever was.  In the face of this avalanche of largess, I don’t feel sorry for DC.  And, any DC residents who really really want to have a vote in Congress can jolly well move a couple of miles into Virginia or Maryland and vote from there. 

Now I hear the Democrat US House as passed a bill to make DC a state, with two senators and one representative.  They say that DC has a larger population than several long standing states.  It got them a lot of favorable press from all the Democratic operatives with bylines.  It would give the Democrats two safe senate seats and one safe house seat.  As a matter of pure politics, as a Republican, I am against the idea.  As a matter of process, I think they would have to do a Constitutional amendment to rewrite Article 1 Section 8.  I don’t believe they can change the Constitution with just an ordinary federal law.

  With Corona virus loose in the land, the economy shut down tight, and George Floyd riots every night, does the country have time for this kind of Mickey Mouse legislation from Democrats?
