"Drinking Kool-aid" is thus code for doing something you know is wrong, but you do it anyway because someone convinced you that you should.

Believing that you can cut costs by spending $1 trillion dollars is... drinking Kool-aid. Blindly accepting that having health insurance guarantees that you will get health care is ...Kool-aid drinking. Promising people they will get free health care even as you drive doctors out of medicine, well, that is lacing the Kool-aid with cyanide.
