D.C.'s 4th EV

[mileslunn]

Constitution specifically states DC cannot have more EVs than any state so unless its get amended and doubt that will happen any time soon.  As long as GOP controls both houses and both legislatures they are not going to want to give the Democrats an extra electoral vote.  Now if the Democrats control both houses and are at some point able to gain control of 3/4 of state legislatures (highly unlikely) then it might be possible.

Also urban areas have generally been declining in numbers.  Yes metropolitan areas are growing as rural areas are declining, but I suspect high cost of housing probably limits how much DC can grow as any growth will just drive up housing prices making it too expensive for most to afford to live there.  As such it is the suburbs as opposed to DC proper where most of the growth is occurring which is growing quite rapidly.  That is a big reason why Virginia is now a blue state instead of red state due to the growth of the DC suburbs which have helped tip it in the Democrat's favour.
