The seat will be vacated by longtime Rep. Henry Waxman, D-Calif., who was first elected to Congress in 1975 and serves as the ranking member of the House Energy and Commerce Committee.
Carr took first place in Tuesday's open "jungle primary," in which the top two candidates from any party advance to November's general election, with 21.5 percent of the seat.
However, Lieu, who collected 19 percent of the vote, is expected to handily win the seat. Greuel recieved 16.8 percent.
