What's at stake in the primary?

Twelve candidates are vying for the seat vacated by Rep. Katie Hill, a prominent figure in the progressive 2018 progressive freshman class who resigned after a messy scandal that divided the nation. Hill became embroiled in scandal after a conservative website published nude photos of her without her consent and accused her of having an affair with her legislative director.

Intimate details of her messy separation from her husband were revealed in the ensuing controversy when the congresswoman accused her estranged husband of abuse and of working with Republican opponents on a "coordinated effort to try to destroy me and the people close to me."

Hill resigned in November amid Republican calls for her to step down. Now, the former two-term Republican Rep. Steve Knight, who Hill beat in the 2018 midterms and whose former campaign advisers ignited the scandal, is running for the rare open competitive seat along with an eclectic field of candidates.

The 25th Congressional District used to be a red swing district but has been trending blue. The special election is taking place at the same time as the regularly scheduled primary, meaning voters will be asked to cast ballots twice, once for the special election and again to nominate a candidate for a new term starting in January 2021.

Ten of the 11 candidates running for the special election to finish out Hill's term are also running in the regularly scheduled primary and general election.

The former Trump campaign aide George Papadopoulos, who was convicted of lying to the FBI in connection with the Russia investigation, is running in the regular primary election for the seat on Tuesday.

The top two vote-getters in the special primary will advance to a special general election on May 12, the winner of which will serve out the rest of Hill's term through January 2021.
