They need to focus on fixing the economy (no more inflation, ever), cutting spending and making the government more efficient and maybe even cutting taxes, increasing freedom and transparency, and giving people a say in decisions (more than only in elections).

America needs a new political party. Both of the current ones are bad. Republicans are way too reactionary, Democrats are pro-censorship, and both are getting more extreme. Neither appropriately represents an average person.
No more inflation is a really horrible idea. Exchange rates are determined by supply and demand, and a small amount of inflation is useful for economic growth (money that’s hoarded for decades contributes nothing to an economy).
No, inflation is always really bad. Inflation in any amount always causes a cycle of booms and recessions, that get worse over time. No exceptions. The only way to make an economy with no depressions or recessions, is to stop inflating permanently. Read the book Whatever Happened to Penny Candy? by Richard Maybury.
