Former member of Congress · last served 113th Congress
Mary L. Landrieu
Mary Landrieu was a Democratic U.S. senator from Louisiana, first elected to Congress in 1997, who voted with most Democrats on 89% of the 112th Congress’s yes/no votes.
How we count: “Broke with party” is a yes/no roll call where the member voted against most of their own party on that vote (party as recorded; even splits not counted). “Pork: own share” splits each earmark shared by several members evenly among them.

Source: MIT Election Data and Science Lab, U.S. House V15 / U.S. Senate V8 (CC0), retrieved 2026-10-18; winners matched to member records by seat and term. Results run through the 2024 elections; nothing from 2026 is shown until it is certified. A margin is a fact about one election, never a score of how well a member represents anyone, and PORKER does not rank members by it.
How has Louisiana done while Sen. Landrieu served?
2005 to 2014 in Louisiana: typical household income was about the same after inflation, the share of people below the poverty line was about the same, and the share of workers looking for a job was down 1.5 points.
Each mini chart has its own scale, fitted to its lines (it does not start at zero), so compare the numbers, not the heights. Oxblood = state, grey = U.S.
While they served, not because of them. This shows what happened in Louisiana during Landrieu’s time representing it (1997 to 2015). It does not say what the member did or caused. It is not a score, and PORKER never ranks members on it.
Survey years start at 2005. The yearly estimates for Louisiana begin in 2005, so 1997 to 2004 are not shown. No 2020 yearly estimate exists.

Read this first. These are counts of records Congress.gov lists. Many bills never get a CBO estimate or a report, so a zero is not a mark against a member. We never show this as a score.
