• OH-06: Republican Rep. Bill Johnson's resignation became effective on Sunday, leaving the House with 219 Republican members and 213 Democrats. Those figures, though, are set to change further in the coming weeks: Democratic Rep. Brian Higgins, who represents New York's solidly blue 26th District, has said he plans to resign in the first week of February, while the vacancy in New York's swingy 3rd District created by Republican George Santos' expulsion will be filled in a special election on Feb. 13.
The vacancy in California's conservative 20th District, meanwhile, could potentially get resolved as early as March 19, should one candidate win a majority of the vote that day. If not, a runoff between the top two vote-getters seeking to replace former Speaker Kevin McCarthy would take place on May 21. Johnson's safely red seat, finally, will go without representation until a June 11 special.
