If Ds win the trifecta they will expand the SCOTUS and make DC a state, that is why Rs need to save the senate at all costs, to protect conservative policies.
Oh yeah, that would really be terrible if those...urban people had representation in Congress!
People of DC have representation in the House which is the popular chamber of Congress (aka the people's chamber), but as DC has never been intented to be a state it is logical you have no senator from the district.
Not voting representation, so it doesn't even matter, and why should someone be disenfranchised based on where they choose to live? The current statehood plan keeps DC stateless, it just makes a new state out of the populated areas.
