In the conservative press I keep reading that this inflation is from Biden. Biden is trying to say that it is the result of Putin and the disruption of petroleum resources. I can't imagine that Joe doesn't have somebody who can tell him the real story, but he wants to play this for popularity - apparently only short-term popularity - so he says this Putin thing to get the heat off.
I think it's worse than this, just because I believe in economies responding only very slowly. The inflation we are seeing is the stimulus check money and the rescue of many businesses. That is on a lot of people, but Donald Trump has to figure prominently in that. Also, supply chain costs gradually coming due.
That means the inflation from the Russian invasion and the inflation from the nightmarish Build Back (Trillions) Better, which, ahem, doesn't actually build very much, hasn't even hit yet. That is still to come.
