I disagree. I think democrats should use their full control to diminish the structural advantage republicans have in the senate via Wyoming, South Dakota, North Dakota, Montana, Idaho. That's their only card left defending them as a national party that isn't accountable to the actions of a majority of the US.
They can't campaign on majority consent nor policy popularity, they have to abuse constitutional procedure and 'statehood', a 18th cenutry concept in and of itself, to delude millions of people that the way they govern is the same as democrats or any other major political party in any developed country on Earth.
Democrats need to induct 3 more states into the union and 4 additional associate justices to cancel out the structural advantage republicans built in the 19th century to ensure our democracy is just barely scraping by.
