@hawkeye10,
I can think of a couple nutty things they subscribe to off-hand:
(1) They think market capitalism will provide a job for each of us sufficient to pay for his/her survival. (In reality it will certainly provide jobs for everyone, but some of those jobs will pay maybe a fourth of what someone needs for survival.)
(2) They think that if you provide for an idle man completely in terms of food and shelter, he will not do any work. (But anyone who subscribes to that belief has never been on the dole. Try getting a girl to date you when you're on the dole.)
Come to think of it, it's not just Republicans who believe those two things. But if you subscribe to those two beliefs, food stamps look like an obstacle to a well-functioning economy.
(And don't get me started on delusions related to science and religion. It's too depressing to think about those.)
