The Democrats do not have a nationally known and nationally popular younger candidate for the 2024 Presidential election.
Nationally, the Dems only have wacko liberal retreads - Bernie Sanders, Elizabeth Warren, Gavin Newsom.
The Dem Congressional gerontocracy has denied younger candidates an opportunity to rise in leadership.
The Dem disdain for Flyover American states means they have no Midwestern moderates or Southern conservatives to appeal to independents. They are left with only limousine liberal elitist coastal progressives.

Kamala Harris is best qualified as a vicodin and wine taster in Napa Valley.
