Election results for representatives [ edit ] In 2018, six Democratic candidates filed statements of candidacy with the Federal Election Commission (FEC).[ 71] Regina Bateson ; Roza Calderon ; Richard Martin; Robert Lawton; Jessica Morse ; and Rochelle Wilcox . Martin and Wilcox[ 72] [ 73]
Retired Air Force Lieutenant Colonel Charlie Brown, who was the Democratic nominee for this seat in 2006 and 2008 , was "seriously considering" running in 2018,[ 74] [ 75] [ 76] 2016 , also endorsed Morse in January.
On the Republican side, McClintock had one challenger, Mitchell Kendrick White , who filed with the FEC in January.[ 77]
In February, the California Democratic Party (CDP) endorsed[ 78] [ 79]
California allows candidates to include their professional description under their names on the ballot. Regina Bateson challenged Morse's ballot designation title of "National Security Fellow" at the Sacramento Superior Court after months of controversy that Morse was "fluffing" her credentials.[ 80] Alex Padilla , struck down Morse's three ballot designations before Judge Gevercer ruled[ 81] [ 82]
Under the California nonpartisan blanket ("jungle") primary system, only the two candidates with the most votes on June 5, regardless of party, went on to the general election on November 6. Two Republicans and four Democrats appeared on the primary ballot.[ 78]
For the November ballot, Morse was also denied "National Security" as her designation.[ 83] [ 84]
