Voters across California are heading to the polls in an election that could reshape the nation's congressional balance, following last year's Proposition 50 efforts.
As a result, several House congressional district races from Northern to Southern California have swung from solid Republican seats to leaning or heavily favored Democratic seats. Local, state, and federal governments are closely monitoring them.
USA TODAY is closely watching the following battleground races across the state: Northern California's 1st District, the Sacramento area's 6th District, the Central Valley's 13th District and 22nd District, and San Diego and Riverside counties' 48th District.
Polls close at 8 p.m. Tuesday; however, residents will quickly start receiving regular
updates from counties. Some of these races may not be decided on Election Day, and officials won't finalize the decision until after Election Day, as county officials continue counting mail and other ballots.
Vote totals will update throughout Election Night. Follow along here as the results come in.
Results from California Congressional District 1 race: Gallagher v. McGuire
California Congressional District 1 was once considered a safe Republican seat, but after the district was redrawn, incumbent Republican Rep. James Gallagher will face a significant challenger in Democrat Mike McGuire.

In June's election, Gallagher received the most votes out of the six candidates, earning 92,975 votes, 42.1% of the vote. McGuire fell behind his opponent by a percentage, earning 92,121 votes, 41.8% of the vote. In total, 220,595 voters cast their ballots.
A recent poll by the Center for the Political Future at the USC Dornsife College of Letters, Arts and Sciences found that pollsters strongly favored McGuire over Gallagher. McGuire leads 54% to 40%, a 14-point margin.
Results from California Congressional District 6 race: Kiley v. Pan
Rep. Kevin Kiley, the incumbent for California's current 3rd Congressional District, faces former state assemblyman Richard Pan in a closely watched race as the country awaits results of California's newly drawn 6th Congressional District.

In March, Kiley announced he would switch his registration from Republican to no party preference. The newly drawn 6th district includes the northern portion of Sacramento County and the southern portion of Placer County and favors Democratic candidates.

In the primary election, Kiley earned 47,165 votes, or about 24.3% of the vote, with Pan coming in second with 45,008 votes, or about 23.2%. In total, 194,217 voters cast ballots in the June election.
A recent poll by the Center for the Political Future at the USC Dornsife College of Letters, Arts and Sciences found that pollsters favored Pan over Kiley 51% to 38%, a 13-point margin.
Results from California Congressional District 13 race: Gray v. Lincoln
Unlike many other districts in California, Republicans hope to flip California Congressional District 13, held by Democratic incumbent Rep. Adam Gray, who is facing GOP candidate Kevin Lincoln, a pastor, U.S. Marine Corps veteran, and former mayor of Stockton.

In June's election, Gray received the most votes out of the four candidates, earning 41,086 votes, 42.% of the vote. Lincoln came in a distant second, earning 27,157 votes, 27.7% of the vote. In total, 97,897 voters cast their ballots.
Results from California Congressional District 22 race: Valadao v. Villegas
California's 22nd Congressional District election has become one of the most closely watched races, as millions of fundraising dollars have been poured into what was once considered a safe Republican seat before Prop 50.
The race features Republican incumbent David Valadao and Democrat Randy Villegas, a community college instructor and political newcomer.
Before the new map, District 22 represented rural portions of Kern County and Bakersfield, with Latino voters who supported Republican candidates in the Valley. The district now represents rural areas in both Kern and Fresno County, with large Latino populations.
In June, Valadao earned the most votes of the three candidates, receiving 32,491 votes, or about 40.7%. Villegas earned the second-most votes, with 25,808, or about 32.4%. In total, 79,757 voters cast ballots during the primary.

A recent poll by the Center for the Political Future at the USC Dornsife College of Letters, Arts and Sciences found that pollsters favored Villegas over Valadao, 52% to 41%, an 11-point margin.
Results from California Congressional District 48 race: Desmond v. Von Wilpert
San Diego City Councilmember and Democratic candidate Marni von Wilpert faces San Diego County Supervisor and Republican candidate Jim Desmond in a toss-up election for California Congressional District 48, which Prop 50 significantly divided.

Before the new map, District 48 was largely rural San Diego County, making it a safe seat for Republican candidates. Congressman Darrell Issa, who currently serves the district, decided not to seek reelection after Californians approved Prop 50.
In June, Desmond earned the most votes of the twelve candidates, receiving 73,508 votes, or about 38.9%. Von Wilpert came in a distant second, earning 39,327 votes, or about 20.8%. In total, 188,951 voters cast ballots during the primary.
A recent poll by the Center for the Political Future at the USC Dornsife College of Letters, Arts and Sciences found that pollsters were somewhat undecided on the two candidates, with neither reaching over 50% favorability.
Von Wilpert leads Desmond, 48% to 40%, by 8 points, according to the poll.
