Louisiana's 1st congressional district

Prior to 1974, the 1st congressional district was entirely south of Lake Pontchartrain. As a result of population changes reflected in the 1970 U.S. Census and a concern to ensure that the 2nd congressional district was majority African American, the district was redrawn to include the Northshore.^{[Source Needed]} This was done to comply with the Voting Rights Act,^{[Source Needed]} passed in 1965 to enforce constitutional rights of minorities in voting, including the opportunity to elect a representative of their choosing and to redistrict after censuses.

In 1974, the state legislature redefined the 1st congressional district, dropping its precincts south of the lake and adding St. Tammany Parish, which borders Lake Pontchartrain on the north, from the 6th congressional district. Subsequently, the 1st congressional district acquired Tangipahoa and Washington parishes, both north of the lake, from the 6th congressional district.

Correspondingly, the 1st congressional district shed conservative St. Bernard Parish and other areas south of the lake to the 3rd congressional district from 1984 through 2013. Overall, the 1st congressional district has become a very safe district for the Republican Party.[5] Before the 1960s, it was controlled by Democrats, but conservative whites realigned with the Republican Party.^{[Source Needed]}

The number of registered voters north of the lake is, as of 2008, slightly higher than south of the lake; however, the 1st congressional district has yet to be represented by a resident from north of Lake Pontchartrain.[6] The reformulation of the 1st congressional district so that it virtually surrounds "the nation's second-largest saltwater lake" has generated a local joke that in the 1st congressional district of Louisiana, the voters are outnumbered by the fish.

The seat was previously held by former governor Bobby Jindal, who was elected after David Vitter retired to successfully run for the U.S. Senate. Republicans have held the seat since 1977. That year Bob Livingston won a special election after Richard Alvin Tonry, who won the seat in 1976, was forced to resign the seat and lost the Democratic primary in the special election.

From 2003 to 2013, the district comprised mostly land on the North Shore and South Shore of Lake Pontchartrain, although it also contained areas west of Lake Pontchartrain. The district included some or all of the following parishes: Washington, St. Tammany, Tangipahoa, Jefferson, Orleans and St. Charles. It also included the cities of Hammond and Slidell and most of the western suburbs of New Orleans, including Metairie and Kenner, along with a small portion of the city itself. The district had the lowest percentage of African-American residents among the state's six-district Congressional delegation.

In 2013, St. Bernard and neighboring Plaquemines Parishes were returned to the first district after nearly 30 years in the Third. The First also picked up much of Lafourche Parish and the southernmost portion of Terrebonne Parish for the first time.
