It's worse than a food fight in a junior high cafeteria: Politicians and bureaucrats are arguing over how many potatoes children should eat.

In one corner of the lunchroom, you've got the U.S. Department of Agriculture, which recently ordered schools across the country to limit spuds to twice a week.

In the other corner, you've got the U.S. Senate blocking that move -- but these aren't brave defenders of personal liberty, or even a child's right to choose potatoes.

Nope.

Instead, you've got senators from potato-producing states terrified about what would happen to their biggest benefactors if the tater tot market went south overnight.

Led by these lawmakers, the same Senate that can't pass even the simplest measures to add jobs, cut taxes or improve the economy, quickly passed a new law -- and it's practically a commandment: Thou Shalt Not Limit Potatoes in School Lunches.

In other words, the official Nanny State position on potatoes in school went from allowed... to limited... to unlimited -- practically overnight!

It's insane.

But forget about the potato. As far as I'm concerned, you can leave potatoes in the dirt where they grow -- because these things are worthless even before you fry them in soybean oil and serve them to children.

No, the real issue isn't the potato. It's why the heck ANYONE in any branch of government -- from the USDA to the U.S. Senate -- thinks they should have any input at all in the content of lunches, school or otherwise.

Expect to see a lot more of this in the coming years -- and no matter how those battles shake out, the end result will be the same: Some potato head is going to be trying to control what your family eats... how much of it they eat... and when they eat it.
