but why are we out of Baby formula?

Because Democrats forced American companies to stop producing it so that China would be able to sell here in America.

When Government uses political clout to force American companies it once shut down to shift their resources to make the stuff they once made before the same government did not want them to make, then that is an abuse of power by the government if not outright fascism in it's purist form.

China isn't shipping formula to the US because they want more money for what we used to make in the US.

And President Biden will pay them soon enough once he knows how big his cut will be.

It's yet another artificial crisis designed to enrich mostly democrats and especially the Biden family.
