Vacancies in the U.S. House will drop from five to two on Tuesday, as three recent special election winners are sworn in. Democrats gained a seat in those elections bringing he partisan composition of the chamber to 221 Democrats and 212 Republicans.
The Democratic gain was in Alaska, where Mary Peltola will complete the term of the late Republican Don Young. Peltola is on the general election ballot, in what will be a special election rematch against Republicans Sarah Palin and Joe Begich.
In New York, Democrat Pat Ryan (NY-19) and Republican Joe Sempolinski will replace incumbents that resigned. Due to redistricting shifts, Ryan will run in neighboring NY-18 in November. Sempolinski did not run for a full term, and has been added to the list of retiring House members.
