To be blunt - the reason you are asking this question is because you (like millions of others) really do not understand the fundamental differences between the Republicans and Democrats. It goes way farther than economics.
Democrats are the intellectual American descendants of the Enlightenment thinkers. Just like many of the socialist and liberal political parties around the world.
Republicans are the indirect descendants of Catholic Thought.
WHAT??? Republicans and Catholic thought? How can that be???
Well, it really has to do with the idea that historic Catholic thought is that true democracy is bad. And that the best possible form of govt is a monarchy (provided you have a good monarch). But since you sometimes there are bad monarchs, therefore, the only acceptable compromise is a republic.
A republic is focused on subsidiary - which is a very Catholic idea. Republics, while they can use democratic elections, are usually protected from mob rule (at least far more than true democracies).
Republicans strongly believe what their name suggests: in being a republic.
Democrats strongly believe in being a democracy.
This is why Democrats typically change their positions with the polls and believe in “voter mandates.” This is also why you have Democrats who say they are personally against abortion but are pro-choice. They feel that America is a Representative Democracy, where the rep must vote the way his/her voters want.
Republicans don’t view it this way. In a republic, you vote for your representatives and then they vote on each issue using their own professional, academic, and moral judgment on each issue. If the representative does a good enough job, they get re-elected. This is why Republicans rarely (at least compared to Democrats) flip on issues. This is also why Republicans are less united than Democrats in Congress.
But really, it all comes down to that key word I said before: subsidiarity. While you rarely hear non-Catholic Republicans use the term, Republicans are practically all in on subsidiarity. Subsidiarity is a concept that is taught in almost all Churches … (even if indirectly) and the majority of Republicans attend Church services. And the pro-life message, is a form of subsidiarity because every individual life is special and every life has the right to life, liberty and to follow the American dream. Which means, a parent doesn’t have the right to end a child’s life.
Obviously, the issues are far more complex than I can write here. But I do recommend this one podcast and then book.
