I'm thinking my first choice would be to create one law which removed criminal penalties for possession and use of all drugs. This bill would allow licensed liquor stores to sell all recreational drugs at a fixed, fair price.
Next up would be a repeal of the appropriations bill which funds the military efforts in Iraq and Afghanistan
Then a law which forbids mortgage holders to foreclose. Let them take out "bad loan" insurance instead.
Prostitution needs to be legalized.
I'd like to see English made the official language of the USA, and remove other languages from anything other than medical care services.
And then I want a pony. :-)
