Dem classism is a much bigger problem for them.
Our system of Electors and the 12th Amendment are setup so a large plurality of states cannot be ignored. If Dems want political relevance, they need to step outside their Safe States - California, New York, Massachusetts - and campaign in flyover and rural states.
Whom did the DNC chose for Chair? Stacey Abrams who helped make Georgia purple - Nope. They chose a failed US Senate Candidate, Jaime Harrison, because he was a better fundraiser.
Dems value money more than votes. That's why they chose a fundraiser over an organizer as DNC Chair.
Dem party has become more of a top-down dictatorship as Nancy Pelosi has consolidated power within her party. Nancy wants Dem primary candidates to be chosen by DNC, not voters, not local Dem committees, and not state Dem committees. It was Nancy Pelosi who decided who would be the Dem nominee for President in 2024.
Hillary Clinton and DNC Chair, Debbie Wasserman Schultz, rigged the 2016 Dem primary so Hillary could not lose, like she did to Obama in 2008.
For all its faults and imperfecions, MAGA has its roots in the People taking the Republican Party back from its out-of-touch elitist establishment.
The Dem Party will probably experience the same fate if Harris loses, and GOP takes US Senate. It was elite Dem progressives who ran two of their own Senators out of the Party and/or the 2024 Senate elections.
