In no particular order:
FairTax.
Range voting.
Very strict separation of church and state. Either appeal to
every religion on the market or none at all (since the former is impossible, the latter wins by default).
Abolish the Department of Education and let the states handle it. If it must remain it would remain limited to ensuring proper nutritional guidelines and making sure the only thing that belongs in science class is science.
The right to bear arms shall not be infringed. (hey that's a good idea, maybe someone should have put that in the bill of rights a long time ago....oh wait).
End the war on Americans who use drugs.
No more corporate welfare.
Start dismanteling private welfare. If you want a check from Uncle Sam you need to do more than fill out a couple applications a week. Work for it. No more multi-generational welfare families.
Enforce international trade regulations. Stop coddling businesses that take jobs overseas.
In whatever state I'm in Uncle Sam stays the hell out of my bedroom.
Uncle Sam also has no business interfering between a pregnant woman and her physician.
The military exists to defend our country, not liberate others or nation-build or secure our financial interests.
Stop the ethanol crap that only farmers will profit from and start focusing money on real energy solutions.
If I buy land I own it from the surface to the core of the Earth - adjusting for geometry, of course.
Government should never be allowed to discriminate but private entities should have no such restriction.
But they should also have zero privacy and must publish employee records as well as policies of discrimination to allow the people to decide whether or not they want to shop at Jimbo's Racist Appliance Emporium.
I'm sure there's more I'd do but that's off the top of my head. If I think of more I'll add to the list.
