I have two horrifying words to answer this question: Justice Palin
Oof, I hadn't thought of that. She's still young, too. Gulp.
She's not a lawyer. You can relax.
Trump may well nominate the most qualified Justices, almost regardless of ideology. That's actually how it used to be before the GOP blocked the nomination of Abe Fortas to be Chief Justice. This was the start of the ideological confirmation fights. It was Herbert Hoover who appointed Louis Brandeis, a liberal jurist, and it was FDR who appointed Felix Frankfurter, who was a Strict Constructionalist. Truman appointed the moderates Fred Vinson and Tom Clark, while Eisenhower appointed liberals Earl Warren and William Brennan as well as centrist Potter Stewart. JFK appointed the liberal Arthur Goldberg, but he also appointed the surprisingly conservative Byron White.
Wasn't Forbas a LBJ hack who had serious ethical issues?
