187 Votes: The Margin That Defined Gray's Seat Before Lincoln's Challenge

California voters in the 13th Congressional District will decide on Nov. 3 whether to keep Democratic Rep. Adam Gray in office or elect Republican Kevin Lincoln to the seat. The contest pits two veteran politicians against each other in a district that was redrawn under Proposition 50.

Gray secured his initial victory two years ago by a margin of 187 votes out of 210,921 ballots cast. He defeated Republican Rep. John Duarte in a race that featured one of the narrowest margins on record for the state. Lincoln, a former Marine and mayor of Stockton, had previously challenged Rep. Josh Harder in the 9th District in 2024. He switched his target to Gray after the new boundaries absorbed downtown Stockton into the 13th District.

The redistricted district covers the agricultural heart of the San Joaquin Valley and extends south along Interstate 5 to the Coalinga area. It skirts the city of Fresno. State records from 2023 indicate that 42.3% of voters in the area registered as Democrats, while 28.5% registered as Republicans. The registration gap provides a slight structural advantage for the incumbent.

Campaign finance data reveals a substantial disparity in resources. As of June 30, the latest Federal Election Commission figures show Gray has raised $4.2 million in contributions and loans. Lincoln has raised $2.2 million. Gray’s financial lead reflects his status as the incumbent, while Lincoln relies heavily on national party support to close the gap.

Lincoln has the explicit backing of President Donald Trump, who declared on Truth Social in December that Lincoln has his "Complete and Total Endorsement." Lincoln described the support as making him "honored and thankful." He features the endorsement prominently on his campaign website. The backing helped him win the primary. However, Democratic strategists argue that high gas prices and aggressive immigration raids will damage candidates associated with the president.

Lincoln has recorded a video for the National Republican Congressional Committee titled "MAGA Majority." The video highlights his time as mayor, his service in the Marine Corps, and his work as a pastor. His LinkedIn profile states he served in the White House Military Office and guarded Marine One from 2001 to 2005. He served as executive pastor at LifeSong Ministries in Stockton through 2020.

Both candidates identify affordability as the central issue of the race, but they propose different solutions. Lincoln states his priority is to "restore the American dream" by making home ownership more affordable. At a September rally, he said he wants to lower the cost of gas, food, and utilities. He also aims to create jobs, cut taxes, and expand healthcare access. He accused Gray of repeatedly voting to raise taxes.

Gray, a native of Merced, serves as a whip for the Blue Dog Coalition. He told the Sacramento Bee, "What voters want here is an independent voice, not a Democratic voice, not a Republican voice." He has called Trump’s deportation policies "irresponsible, reckless, dangerous." Gray cites his work to reverse Republican Medicaid cuts and limit presidential tariff powers without congressional approval. He also introduced a measure to reduce regulations on thermal energy. Lincoln counters by noting that Gray "increased the gas tax over 113% a gallon" while serving in the California Legislature.
