this is fundamental underlyinng reality that will kill the prospects of any established democrat. if they are so "able to defeat trump" then why didn't you run them instead of harris? you could have picked anybody. you had an open convention because the primary only gave delegates to biden. with complete freedom of choice the party chose kamala, so you got exactly the person you wanted. there is no "big name" democrat that people want, you have to face that fact.
