President Trump is racking up federal judicial appointments, and not just to the Supreme Court, where his second nominee, Judge Brett M. Kavanaugh, is set for confirmation hearings this week. So far, he has filled 60 seats on the federal district courts, the courts of appeals and the Supreme Court.

Marvin Quattlebaum Jr.’s seat on the District Court for the District of South Carolina is shown as vacant, as he was confirmed on Aug. 16 to the Fourth Circuit.

Mr. Trump came into office with more than 100 judicial vacancies, and relaxed Senate rules on confirmations have allowed him to fill them quickly. Senator Mitch McConnell, the majority leader, has said confirming Mr. Trump’s nominees is his “top priority.”

Mr. Trump’s 26 appointments to the appeals courts have raised the overall number of Republican appointees, and if he fills the 13 existing vacancies, the majority of judges on the appellate level will have been appointed by a Republican president.

But he has fallen short of “flipping” the balance of appointees on any individual court. He has strengthened the existing conservative majorities on four courts, but eight courts still count a majority of judges who were appointed by Democratic presidents. The 11th Circuit is now an even split.

Experts often look to the party of the appointing president to assess whether a judge might lean conservative or liberal. Although it is not an exact predictor of how a judge will rule on a given case, said Lee Epstein, a law professor and political scientist at Washington University in St. Louis, “it gives you some information.” Professor Epstein said, “In general, Democratic judges are more liberal than Republican judges, but not every judge and not every case.”

Just as on the Supreme Court, Republicans and Democrats look to secure a majority of appointees on the appeals courts. Appeals cases are primarily heard by panels of three judges, and the makeup of an individual court affects the makeup of a panel. “If you have a circuit that is one-third Republican and two-thirds Democratic, you would expect the panels to roughly reflect that composition,” Professor Epstein said.

Trump is moving more slowly on the district courts

Mr. Trump inherited so many judicial vacancies thanks to Mr. McConnell's decision to all but block President Barack Obama’s nominees starting in 2015. He has worked quickly to fill seats in the appeals courts, but when it comes to the district courts, which conduct trials for federal cases, he lags behind most of his recent predecessors with 33 appointments so far, though eight more are expected this week.

Trump could see fewer Democratic vacancies in the future

Over all, 134 vacancies remain on the appellate and district courts, and 74 nominees are pending. Mr. McConnell has said he hopes to confirm all pending nominees before the end of the year.

That would mean about one in seven federal judges would have been appointed by Mr. Trump. Yet Mr. Trump may not see many more Democratic vacancies to fill on the appeals court, which would give him the opportunity to flip courts, in the near future.
