Obama was better than Biden, honestly
Biden is more effective and much better on foreign policy
They're similar on foreign policy, I'll grant you that Biden is better at working with Congress than Obama was. It's mainly on domestic/economic policies where I think Obama did better.
I don't think they're that similar honestly. Compare how Biden handled Russia's invasion of Ukraine to how Obama handled Crimea in 2014. Also, in general Biden's foreign policy has been more coherent, and in general less flawed than Obama's was. In terms of Domestic/Economic Policy, I agree Obama had a deeper hole to dig the country out of economically, and to his credit he did keep it from getting worse, but the recovery was, until his 2nd term, weak and in general was very uneven. I do think given the majorities he had in 2009-10, he could've accomplished more than he did, whereas if Biden had anything close to Supermajorities in 2021-22, we'd have a modern New Deal or Great Society today.
