Cutting government is the conservative trait most in demand.
Make me dictator for a month. If I don't step down, you can shoot me. First thing I'd do is do a 1-for-1 comparison of every government agency. If there was no power given to the FedGov for an agency to have, then that agency would get the axe. Next, I'd assemble a legal team with One Mission and one mission only; scrub the US Legal Code of all laws that violate the US Constitution and the Bill of Rights on a plain reading of their words. No stare decisis allowed. Anything not meeting muster would be dumped into an omnibus reform bill to be sent to Congress for repeal.
If Congress refuses to pass said bill, they would be tried for treason and shot. On the floor of the Congress if necessary.
Next, all State laws that violate the US Constitution and the Bill of Rights, would be required to be repealed. Failure to comply will result in that States expulsion from the Union and trade barriers erected. That oughta cut off the Blue States effectively. Red Counties in Blue States would be encouraged to band together and petition for Statehood.
If I had any time left after that, I'd try and get the popular election of Senators repealed. Get a "unanimous Consent" doctrine in place instead of simple majority. Instant Run off elections complete with an office vacancy provision if no clear majority winner can claim victory. Repeal the public dueling statutes. Small stuff.
