Right in the middle of the Central California coast is a district that is more conservative than the rest of the state's coastal areas. Centered on San Luis Obispo County, including most of Santa Barbara County, and a small northwest portion of Los Angeles County, this area has almost always sent Republicans to the state Legislature or to Congress. The exceptions have come when the area is split, pushing half its population to the north or south, or pairing it with equally conservative inland districts. The Supreme Court did not do that, making this district safe for Republicans. This district is 6% African American, 3.4% Asian, 30% Latino.

District 23 (46.63% D - 27.46% R - 20.59% DCL) - Lois Capps - MAP
Central Coast district encompassing parts of San Luis Obispo, Santa Barbara, and Ventura Counties. Home to coastal communities such as Cambria, Morro Bay, San Luis Obispo, Arroyo Grande, Santa Maria, Santa Barbara, and Oxnard. This district is 1.9% African American, 5.5% Asian, 45.4% Latino.

The northern part of Los Angeles County in the Antelope Valley (Palmdale, Lancaster and Santa Clarita) is more akin politically to the Central Valley than to the rest of the county to the south. This district includes all that area and dips over to pick up Chatsworth and Northridge from the San Fernando Valley as well. Indeed, this part of the county at times has tried to split off and form a new county of its own. San Bernardino, Inyo, and Mono counties are also found in this district. It's solidly Republican. This district is 9.5% African American, 5.2% Asian, 38.2% Latino.

District 26 (35.14% D - 40.23% R - 20.47% DCL) - David Dreier - MAP

The suburbs north of downtown Los Angeles, including Burbank, Glendale, Pasadena, and La Canada. The politics here are Republican even though nearly 40 percent of the population is minority. The trouble is, most of the minority population isn't registered and doesn't vote. Latinos, for example, make up 20 percent of the population but fewer than 8 percent of the registered voters. This district is 4.4% African American, 11.9% Asian, 41.5% Latino.

District 28 (56.32%D - 17.18%R - 21.82% DCL) - Howard L. Berman - MAP

District 29 (45.37% D - 26.15% R - 24.16% DCL) - Adam Schiff - MAP
The affluent communities of Los Angeles' westside, including Beverly Hills, Santa Monica, Westwood and Hancock Park, have been collected into this solidly Democratic district that has been dominated by liberal Jewish politicians.

District 30 (50.57% D - 22.83% R - 22.08% DCL) - -Henry Waxman - MAP

This district is 4% African American, 14.2% Asian, 69.1% Latino.

District 32 (51.19% D - 22.83% R - 21.86% DCL) -Judy Chu - MAP

With the largest Latino population within the California congressional delegation, District 34 includes portions of Los Angeles, the cities of Downey and Huntington Beach. The Latino population is an overwhelming 80.6%, trailed by 5.9% Asian, and 4.1% African American. It is a safe democratic stronghold.

District 35 (66.39% D - 12.79% R - 16.79% DCL) - Maxine Waters - MAP
The most Democratic congressional district in the state includes the cities of Inglewood and Hawthorne as well as south-central Los Angeles. The district's population is 29.4% African American, 52.9% Latino, and 5.7% Asian. The new district stretches towards the beaches south and east of Hawthorne, diluting its Democratic base, but not threatening Maxine Waters' incumbency.

District 36 (45.33% D - 27.57% R - 22.15% DCL) - Jane Harman - MAP
This district runs along Santa Monica Bay from south of Santa Monica through the Palos Verdes Peninsula and includes the cities of El Segundo, Manhattan Beach, Redondo Beach, Torrance and Lomita.

The fourth strongest Democratic district in the state, it includes parts of Los Angeles as well as the cities of Compton, Carson and the downtown portion of Long Beach. Formerly a Republican seat held by Steve Horn, it is over 60% registered Democrat, with a large minority population of 82%, with the largest ethnic group being that of Latinos, who make up 49% of the population. Asians make up 11.8% while African Americans make up 21.3%.

District 38 (55.9% D - 21.14% R - 19.12% DCL) - Grace Napolitano - MAP
This district encompasses the ethnically mixed working class communities of Pomona, Norwalk, Pico Rivera, and Montebello. Formerly CD 34, this district remains substantially Latino at 75.6%, followed by 10.3% Asian, and 3.1% African American. The district had gone Republican through the first half of the 1990s, but the races all were competitive and registration favors Democrats enough to keep it that way until the next redistricting.

District 39 (51.84% D - 25.46% R - 18.65% DCL) - Linda Sanchez - MAP
One-third of this district's voters live in the Los Angeles County communities of Cerritos, La Mirada, and Paramount. This district formerly had a small portion within Orange County but was recently drawn to remain entirely within LA County, thus providing a relatively safe Democratic seat. These LA voters are predominantly Democratic with 52% registration compared to a 25% GOP contingent. The district has a large minority population -- 65.9% Latino, 10.6% Asian, and 5.0% African American.

District 40 (33.39% D - 42.5% R - 19.83% DCL) - Edward R. Royce - MAP
This Orange County District includes the communities of Orange, Fullerton, and Buena Park. It is a relatively safe Republican seat with an closely split White (40.6%) and minority population of 34.8% Latino, 19.2% Asian, and 2.7% African American. This oddly shaped district carefully surrounds the city of Anaheim, avoiding Anaheim Democrats to secure the GOP's incumbency.

District 41 (33.1% D - 44.4% R - 17.15% DCL) - Jerry Lewis- MAP
A 29% minority district split between San Bernardino and Riverside counties. Republicans outnumber Democrats here, thanks to conservative voters found in Redlands, Colton, and San Jacinto, among others. More than 80% live within San Bernardino County, a safe GOP county. Only 32.6% of the district is Latino, which is overwhelmingly White (53.5%).

District 42 (30.05% D - 45.82% R -20.27% DCL) - Gary Miller - MAP
A GOP district that includes the counties of San Bernardino, Orange, and Los Angeles, and includes the cities of Mission Viejo, La Habra, Anaheim, and Yorba Linda. It maintains only a 40% minority population, with 28.4% Latino, 18.3% Asian, and 2.4% African American. CD 42 has experienced serious tension during the 1990s as Republicans ousted liberal veteran Democrat George Brown Jr. with Republican Gary Miller.

District 43 (49.07% D - 29.64% R - 17.43% DCL) - Joe Baca - MAP
Found entirely within San Bernardino County, CD 43 contains the cities of Ontario, Rialto, and Fontana. The majority of the population is made up of Latinos (67.4%), trailed far behind by Asians (3.8%) and African Americans (10.4%). This district swallowed up Ontario to provide incumbent Joe Baca a safe Democratic seat.

District 44 (33.47% D - 43.36% R - 18.46% DCL) - Ken Calvert - MAP
Including the Orange and Riverside counties of San Clemente, Riverside, and Corona, the district is more than a third minority, with Latinos alone accounting for 43.1%, followed by 5.6% African Americans, and 6.2% Asians. CD 44 has and will probably remain a safe Republican seat for incumbent Ken Calvert.

District 45 (38.14% D - 41.39% R - 16.12% DCL) - Mary Bono Mack - MAP
Within Riverside County and a historic GOP bastion that incorporates the communities of Coachella, Moreno Valley, and Palm Springs, it is more than 42.6% white, and has 43.9% Latino, 6.1% African American, and 4.5% Asian. Despite voting for Davis in '98, CD 45 was drawn to provide a safe haven for Republican incumbent, Mary Bono.

District 46 (31.5% D - 43.21% R - 20.57% DCL) - Dana Rohrabacher - MAP
A 75% non-minority district in Los Angeles and Orange Counties that is only 19.1% Latino, 18.2% Asian, and 1.4% African American. It includes the cities of Avalon, Costa Mesa, Huntington Beach, Seal Beach, and the wealthier Rancho Palos Verdes and Rolling Hills. This district was drawn to isolate Palos Verdes Republicans who troubled the Democrats throughout the 1990s. It is a safe seat for the GOP.

District 47 (46.79% D - 30.85% R - 18.83% DCL) - Loretta Sanchez - MAP
Interior Orange County is relatively safe Democratic territory. It includes only portions of the cities of Santa Ana, Anaheim, and Garden Grove. It is home to a growing Latino population (69.8%), which should make it a safe Democratic seat, but maintains a Republican-leaning contingent that voted for Bill Jones in '98 for Secretary of State. It also has a 14.8% Asian and a minuscule 1.2% African American population.

District 48 (28.92% D - 44.15% R - 22.73% DCL) - John Campbell - MAP
Orange County district which includes Aliso Viejo, Dana Point, Irvine, Laguna Beach, Laguna Hills, Laguna Niguel, Laguna Woods, Lake Forest, and Newport Beach. It is a safe Republican district with a small minority population, including 16.6% Latino, 17.2% Asian, and 1.5% African American. Held by incumbent Chris Cox, CD 48 represents the state's strongest GOP seat.

District 49 is primarily composed of the geographic area that was formerly District 48. Voters in this region have elected republicans as their representatives for the past two decades.
