Eh, but you have examples of long-term problems created by each president: you had Clinton’s half-baked Eastern European legacy, Bush II’s middle east legacy that lasted a while, Trump’s completely polarised political landscape. I’m not sure what Obama’s main fuckup was, but there were many small neglects (maybe the main one was how he handled the 2008 crisis that Bush II left him)…the more influence you have as a country and as a person, the more shit falls on your plate to deal with :/
