No, but it isn't his fault that close to half the country, and the political party that represents them, is irredeemable.
This, pretty much. Initially, yes he did, and still kind of - in the sense that America is more respected than we were doing the Trump years. But the toxicity of Trump, his campaign, his followers, and 1/6, basically made this mission impossible for the time being.
Its sad but between the hardcore MAGA crowd, Khmer Rouge leftists who hate him it is impossible for him to maintain good approvals. It is time for the left to face how cancerous Bernie Sanders campaigns have become over time (yes, this movement is directly connected to them and has NONE of the optimistic tone Obama struck in 2008).
