Well let's ask Trump who was the last great president besides himself of course
"I think Bill Clinton was a great president,’" Trump said in the interview that was conducted shortly after the 2008 presidential election on NY1's "Inside City Hall" program. That was after 8 years of Bush.
"You know, you look at the country then. The economy was doing great. Look at what happened during the Clinton years. I mean we had no war, the economy was doing great, everybody was happy. A lot of people hated him because they were jealous as hell,’" Trump said.
And based on that comment, Biden was great too. Economy is great, no war, everyone but conservatives happy (it's why they voted for Bush 2, twice).
Republicans were jealous.
Republicans, like every non incumbent on the planet, benefited from inflation. Every incumbent lost or took the blame. So it's not just American voters who are stupid.
