I think your explanation has best explained it - you see it more as both parties sort of upholding an undemocratic status quo (as you said, Republicans actively doing x activity with Democrats either not doing enough to counteract or being implicit) rather than the Dems/Biden offering a tangible actual long-term change. I understand as well that the party had better candidates than Biden/Hillary but the candidacy is heavily dependent on funding/donations, which is wildly inequitable. Thank you for taking the time to explain, very informative.
