Can President Trump 'pack' the federal court system?

Judge Neil Gorsuch is likely to be confirmed to the US Supreme Court, and there may be other vacancies in the next four years. In addition, 124 judicial benches are open in federal appellate and district courts all over the country, and more retirements are inevitable. As long as Republicans dominate the Senate, there's a real chance that Mr. Trump could push the system to the Right for generations. That's been the goal of so-called "dark money" spent by shadowy billionaires to make American institutions more to their liking.
