There is some blame that goes to the Biden & the administration. I would argue that of all the topics you mentioned, proportionally most of it isn't Biden's fault, but some is.
-Inflation was going to happen regardless of who won the 2020 election. Inflation is a global issue that several countries are facing. But the American Rescue Act did help contribute to inflation here. Without it though, the economy would most likely have not recovered as strong and quick as it did, and businesses and city/state governments would have not been saved in the quick way they were. So I'd argue that it was a necessary sacrifice, but perhaps way too much money was in the package. $1.9 trillion to an already overheated economy is asking for serious smoke. And the Treasury Secretary did admit that she was wrong when she stated last year that inflation would be a small risk, but manageable and not a big problem. Which is essentially miscalculation and to some degree incompetence. They were looking at getting the economy going ASAP without thinking about any potential long term impacts.
-Stagnant wage growth is probably what this economy needs right now if it can be part of a process that cools down the economy and reigns in inflation. There was good wage growth, but inflation clearly is outpacing that.
-I don't think gas prices is Biden's fault. Even with the sanctions that were put on Russian Oil that Biden himself stated would lead to higher costs at the pump. Because gas prices were already rising with projections that they would continue to rise. I do think it was a stupid political move by telling Americans "yeah you gotta pay more at the pump because fukk Russia." That's just going to piss people off and get Fox News/GOP to control the narrative regardless of polling stating that there was support behind the move. People are already hurting. Telling them they have to hurt more just isn't smart.
-Biden apparently wasn't told there was a baby formula shortage until April when apparently retailers were getting notification months before that. Someone screwed up because Biden should have been told sooner. I do give Biden credit because once they got moving on it, he used Executive Orders to get military planes to bring over the product and used the Defense Production Act to get moving on it.
-I don't think he's failing on the international stage. The withdraw of Afghanistan was needed even though it was chaotic, and the 13 dead marines really did put a negative stamp on the withdrawal. But he'll ultimately he remembered as the President that finally got us out of there after 20 years. Contrary to people here in TLR and GOP nationalists, I think he's doing a solid job with the Ukraine/Russia war and historically I think he will be remembered as the President that brought NATO closer together than its been in decades when people didn't think that was possible. Even Cozzie Rice and other conservatives have given him credit on that.
As of now, Biden is looking like a failed one term President that will lose to Trump or DeSantis in 2024. If I'm being honest with you though, I don't think he's doing a bad job as President. Everything that can go wrong just seems to be happening all at once or back to back to back. And there's no real optimism, hope, or confidence in the current direction of the country among the American people. Some of which is out of his control, but when you're the President, you get credit for everything good and blame for everything bad. That's just how it is.
Unlike Reagan, Clinton, Obama, or even Trump (for all the wrong reasons), Biden is not a charismatic guy that can spark confidence and hope in people. Those type of people are able help shape narratives and install confidence in people even during tough times which can help them politically. He's a boring, dull, old, and sometimes slow man and that does nothing but have people giving him the side eye.
