Republicans are unconcerned with the actual effects Biden policies have had on inflation. They'll simply say inflation is out of control, the economy is collapsing, and it's all Biden's fault. Their messaging isn't constrained by the truth; their voters will believe anything.
The rate of inflation may be falling, but year on year it's still rising. I mean, I don’t know about you, but the cost of living certainly doesn't feel like it's getting any easier.
