Primary: California has a top-two primary system, in which the top two vote-getters, regardless of party, go on to the general election.

Incumbent: Heading into the election the incumbent was John Campbell (R), who was first elected in 2005.
This was the first election which used new district maps based on 2010 Census data. California's 48th congressional district is located in the southern portion of the state and includes most of the Orange County coast.
This was the first election year in which California's Top Two Candidates Open Primary Act was in effect. Because of this, all candidates for a seat competed in one blanket primary. The two candidates who received the most votes then advanced to the general election on November 6.
The proposition's intent was to encourage primary competition, which backers of the act said would lead to more moderate legislators being elected. Despite this intention, only a few centrists successfully advanced to the general election. The primary results did reflect an increase in competition, with California's percentage of contested primaries being much higher than the nationwide average.
However, the increase in competition also led to an increase in campaign spending, due to the fact that competition within political parties lasted for the entire year rather than ending after the primary. Experts predict that this will only increase the power of the special interest groups that fund the campaigns.
Raphael J. Sonenshein, executive director of the Edmund G. "Pat" Brown Institute of Public Affairs at Cal State L.A., said the following, "It's hard to argue it's a better system where the incumbent congressman has a huge war chest and nobody else has any money... At least now we can make him spend it."
As a result of the blanket primary, nine of California's 53 congressional districts had same-party candidates battling in the November 6 general election. Of those, seven were between Democrats.
Note: Election results were added on election night as races were called. Vote totals will be added when official election results are certified. For more information about Ballotpedia's election coverage plan, click here. If you find any errors in this list, please email: Geoff Pallay.

In 2012, FairVote did a study on partisanship in the congressional districts, giving each a percentage ranking (D/R) based on the new 2012 maps and comparing that to the old 2010 maps. California's 48th District became more Republican because of redistricting.
- 2012: 44D / 56R
- 2010: 45D / 55R
