19 seat numbers with no sitting judge
These are seat numbers in the historical record with nobody currently in them. That usually means the seat was abolished or renumbered, not that it is open today — Congress has changed the size of federal courts many times. Do not read this as a vacancy list.

This site does not publish a vacancy count. Seat identifiers are not stable across court renamings and reorganisations, so a seat that was vacated and refilled can appear empty when it is not. The Administrative Office of the U.S. Courts publishes the authoritative list of current judicial vacancies: uscourts.gov.
Seats are created by Congress and filled by the President with the Senate's consent. For current vacancies, use the Administrative Office's published list rather than inferring them from this table.

The party of the president who appointed a judge is a matter of record. How that judge will rule is not, and this site draws no inference from one to the other.
