Well, I about choked and laughed at the same time when I saw "monarchist" in the OP - perhaps that means something else in the USA, but anyway. . .
1) Closing about 75% of overseas military bases and greatly reducing foreign aid
2) Legalizing, controlling, and taxing Marijuana
3) More progressive tax system - 75% at the very top
4) End the death penalty - life sentence the max
1 and 2 are probably not nearly as far out of the mainstream as 3 and 4.
none of those are actually out of the mainstream as far as public opinion goes.
I hope you're right; I think it depends on region - but I don't think it's mainstream to end the death penalty, although it's an issue that hasn't come up much recently nationally.
