Groceries in the U.S. remain expensive; more states want to stop taxing them

They'll still tax the income used to buy the groceries, the profits made from selling them, the properties used to store and prepare them, the automobiles and fuel used to transport them, and the payroll of the companies selling them.

Well, everyone needs food, but not everyone needs luxury items. Lowering taxes on basics like groceries and raising them on luxury items or even better, raising income tax for the rich, would be way better.

In general sales tax isn't a significant source of revenue for states, to the point where some states don't tax retail sales at all.

It's not up to the President to do everything that needs doing. Presidents make stupid promises they can never fulfill all the time; this has been the case going back decades at a minimum, and probably further than that. It's really annoying how people have this delusion about just how much power Presidents have.
