Like who? Biden a puppet with dementia, Obama invading Libya and helping kill Gadaffi (and actually killing his family), as well as drone strikes on individuals in lots of middle eastern countries, Bush and Iraq/Afghanistan, Clinton and .. Iraq? but also war on drugs and Mexico border fence. Previous Bush - Iraq again?? Before that, South America again.
Biden became worse in the last year, but he wasn't a 'puppet', certainly not like the current president is. I'm not a fan of Obama's actions but he at least gave justification instead of inventing it and lying like Bush.
Kamala was the obvious choice and the only adult running in the last election, but she lost largely due to sexism, racism and gullibility of the red state population.
Assuming we get to have another election, we'd hopefully have someone like Bernie or Elizabeth Warren.
