As of 2015, results from all Louisiana elections dating from 1982 to the present are available from the website of the Louisiana Secretary of State. This data includes primary elections, special elections, general elections and runoffs.
The election data available from the state of Louisiana includes raw vote numbers for particular issues, candidates and statewide tickets as well as percentages gained. These include national races for President, Senate and U.S. Representative when these elections occur, as well as results from the state legislature and local precincts.
The State of Louisiana employs an open primary system in which all candidates for an office run together for election. If no candidate gets a majority of all votes, the candidates with the highest vote totals go to a runoff election. Runoff elections are common in the state, delaying many crucial results until a runoff can be held.
