What You Need To Know

  • GOP incumbent Mike Garcia leads Democratic challenger Christy Smith by 422 votes in 25th Congressional District race

  • Garcia added 318 votes to his lead in Tuesday's count

  • The race is to fill a seat vacated by former Rep. Katie Hill, who resigned following a scandal

  • It is not known how many votes remain to be counted

It was unclear how many ballots from the Nov. 3 election remain to be counted in the district.

Garcia had led by 104 votes entering Tuesday's count.

The race has remained close since election night. As ballots were tallied over the course of last week, the lead changed hands twice. Smith, D- Santa Clarita, at one point had a 1,287-vote lead, but Garcia, R-Santa Clarita, erased that advantage and took a narrow lead.

The 25th Congressional District stretches from the Antelope Valley into Ventura County. Vote by mail ballots will continue to be accepted through Nov. 20 if they were postmarked by Election Day.

Garcia defeated Smith, 54.86%-45.14%, or 95,667-78,721, in a May 12 special election to fill the final 7 1/2 months of the term of former Rep. Katie Hill, D-Agua Dulce, who resigned following the online release of salacious photos and allegations of an extramarital affair with a staff member.

The seat had long been held by Republicans until Hill's 2018 victory over then-Rep. Steve Knight, R-Palmdale.
