I only made that list to point out that you need a lot more than a vitriolic sentence of intent to rally a political party. But hey, I get a chance to pick Strife's brain, what fun.
Amend the Constitution to declare arms to be an individual right, and not restrict anything less than LMG's.
What exactly is that supposed to mean? How is the language of 2nd Amendment not adequate? What about ammunition types? Stockpiling laws?
Sales Tax: Probably end up raising it, just to fund assorted other programs.
I just threw this in as it hit my mind. There is no national sales tax (specifically so anyway), and every state has it's own constitutional rules about how sales taxes work. That's important for a party operating in different states though.
Loans: Federal guidelines on the interest chargeable, as well as schools advertising them. Possibly let the Federal Government give out student loans.
That's exactly the point. Right now, the federal government subsidizes banks to make student loans. We've since figured out it would be simpler and cheaper (or more effective if the funding stays the same) for the federal bank to just make the loans itself. There's a not inconsequential number of Congressmen who don't like this idea.
Infrastructure: Light a fire under the works departments (and everyone else, really). Get the states to pay for most of it.
America's infrastructure is crap precisely because nobody's paying for it anymore. Most states have very strict rules about budgeting, and have written off infrastructure, especially highways and waterworks, as the federal budget's responsibility. At the same time that American political culture, especially in Congress, regards infrastructure as a naturally occurring phenomenon. All comes back to the same question, where ya gonna get the money?
Nuclear Disarmament: Not a chance in hell.
America's stockpile of nuclear warheads could annihilate the entire Earth landmass eight times over. Our Trident submarine fleet alone could level every strategic population center on the planet in thirty minutes with plenty of ammo to spare. How many times do you need to end the world are we preparing for? Let's compromise at two, just in case the first doesn't take.
Medicare, Tariffs, Research Grants
Doesn't look like either of us is much qualified to argue about this one. Just an endless revolving litany of, "I dunno".
