I'd make my top priorities these:
1. National security. This means fighting the war on terror, protecting our borders, and deporting anyone who doesn't belong here. Note to the left - that means deport them even if they are voting for you. Note to the right - that means deport them even if they are working cheaply in your factory or cleaning your house or babysitting your kids. Note to those who complain about the cost - We'll more than make up the cost in reduced health care fees, reduced strain on the court and prison systems, fuller employment for citizens and those here legally.
2. Tax reform. Abolish the IRS. Abolish income tax and estate tax, and corporate taxes. This will also help a great deal with #1 by closing many of the loopholes for terrorist money laundering. It will also help with #3 by keeping the likes of Hillary from using the IRS to blackmail enemies and coerce on "friends".
3. Clean house in the justice system. It should provide justice for ALL of us. Justice means sending criminals to jail. It does NOT mean that if the criminal is rich and can afford a pricey lawyer that he gets off. It does not mean that the rich get to "buy" laws by buying legislators. It does not mean that if you commit murder, but you can manage to find a case where another murderer got a lighter sentence that you should get a lighter sentence, too. When the citizenry no longer has faith that it will be protected by the law, productivity and security decrease. Fixing the justice system will also help with #1.
5: A more independant foreign policy. We should not be waiting for the aproval of the UN or our 'allies' to take actions vital toour national security. While we wait for world approval Iran is busy making a nuclear bomb.
