Freshman Rep. Lucille Roybal-Allard (D-Los Angeles) is considered a heavy favorite to recapture the 33rd Congressional District seat she won two years ago.
Roybal faces only one challenger in the primary, a political newcomer making his first bid for elective office, and there are no Republican candidates.
Roybal-Allard, 52, succeeded her father, Edward R. Roybal, who represented the 33rd District for nearly 30 years before his retirement in 1992. She won easy victories in the primary and general election in that same year.
Roybal-Allard's Democratic challenger is Charles E. Green, 73, a self-described human-rights advocate who says he served 10 years on a senior citizens' advisory panel to the state Legislature.
The winner will face Peace and Freedom candidate Kermit Booker, 57, a teacher at Lynwood High School.
