1. Overturn Roe v. Wade
The abortion issue is what's called a wedge issue--the ultimate wedge issue, it seems--that inures to the benefit of the Republican party and ultimately rich people of both parties. Abortion splits the middle class right down the middle. Half of those middle-class people vote Democrat, the other half Republican. This allows rich people and evangelicals to control the Republican party and rich people, poor people and kooks (mostly kooks) to control the Democratic party. The result of this division has been the resolute decimation of the middle class over the last 5 decades since Roe v. Wade was decided.
Without Roe v. Wade, both parties would have to tailor their respective platforms and policies in favor of the middle class, rather than the rich and the poor. Franklin Roosevelt was the first politician to harness the power of the middle class, and he won four terms in office, followed by a fifth for his Vice-president, Harry Truman. The run was only ended by General Eisenhower, a war hero, who was a Republican, but whose policies were in no way different from those of Roosevelt/Truman, and who was anchored by a Democratic Congress throughout his eight years in office. He was followed by eight more years of Democratic hegemony. This was an era of unparalleled prosperity. A return to a pre-Roe national political landscape would invite back those years of growth and stability. It would make both parties much more sensible.
Middle-class people tend to be rather no-nonsense in their approach to life. The extremes of the social liberals that have a stranglehold on Washington, DC today would take a back seat to normal, middle-of-the-road middle-class values. This would be the best thing for the poor, as well. A thriving and attainable middle-class to which they can aspire and thrive is far more effective at raising them out of their poverty than any government giveaway program could ever be.
2. Expand the Definition of Religion
Realizing and legally recognizing through court precedent that certain worldviews hold no distinction from historical religions would go a long way toward leveling the playing field of politics and education. Religions like LQBTQ+, Climate Change and even Science in general currently are allowed to indoctrinate throughout society with impunity, particularly in schools. "Outing" them as religions would mean they could no long fly beneath the radar. People would still be able to practice these nihilistic and atheistic religions but they would no longer be allowed to use the airwaves to proselytize and preach that their way is the truth and all other religions are false.
