Congressional candidates are not required to live in the districts in which they are running, but they are often criticized if they don't.
Under the U.S. constitution, the only residency requirement is that a U.S. House member must live within the state he or she is representing.
It does not further require them to live within a specific district within that state.

アメリカにおいて代表する地区内に居住する必要はないが、地区内に居住していない事はしばしば批判の対象になる
代表する州に住んでいればOKらしい
Sacconeの場合、今まで想定された事のないような事態だから多めに見てもらえるか
