Here’s a small sample of the outrageous waste of federal tax dollars, as detailed in a GAO report scheduled for release today.

Government agencies are spending billions on new mapping data — without checking whether some other government agency already has maps they could use.

• At least 23 different federal agencies run hundreds of programs to support renewable energy.

• Each branch of the armed services is developing its own camouflage uniforms without sharing them with other services.

Remember this when someone tells you it’s just not possible to scale back federal spending.
