In 1964, before the passage of the Voting Rights Act, less than a third of Louisiana�s voting-age blacks were registered to vote, but the percentage varied widely from one parish to another--ranging indeed from 93.8 percent in Evangeline Parish to only 1.7 percent in Tensas. By 1968, however, almost 59 percent of age-eligible African Americans were registered, and in some parishes the change was very dramatic.

This is the picture today, when just over 32 percent of the state�s population is black, a proportion that ranks as the second highest in the country:

• The initial goals of the Voting Rights Act have long since been achieved in Louisiana. After each election, the US Bureau of the Census issues registration and voting data based on the self-reports of a sample of individuals. From 1980 to 2004, white and black self-reported registration rates were quite similar�both above 70 percent with the exception of only two years. Moreover, the percentage of the state�s registrants who are black has equaled or exceeded the black share of the voting-age population. Black registration, in other words, is disproportionately high in relation to the eligible black population.
  
  
• In that same time period (1980 to 2004), blacks in Louisiana have reported higher registration rates than blacks outside the South. In fact, beginning in 1988, the difference has been at least ten percentage points, with the one exception of 1994. In 2002, Louisiana blacks were 16.5 percentage points more likely to report being registered than non-southern African Americans.
  
  
• The Census Bureau also surveys turnout (self-reported as a percentage of voting-age population). In presidential years in this same time period, at least 60 percent of voting-age blacks report casting a ballot; in 1992, the figure was 71.5 percent. At times, the proportion of actual voters who are black has been higher than the percentage of black registrants. Whites turned out at similarly high rates. White and black turnout differed little even in mid-term elections, when, by law, no state officers run and the general election is only for those seats for which no candidate got a majority of votes in the first round--two factors that depress turnout. 
  
  
• In presidential years, Louisiana blacks always turn out at higher rates than in states outside the South. In 2000, the difference was 10 percentage points. That has generally been the case with midterm elections as well. 
  
  
• Louisiana is one of the few states collects actual registration and turnout figures by race, but, unlike the self-reported (and thus less reliable) Census data, these figures cannot be used for making interstate comparisons. Nevertheless, they are informative. They show, for instance, that since the passage of the Voting Rights Act, black registration increased five-fold, and by 2004, blacks were almost 30 percent of the registered electorate, a figure basically identical to the voting-age population.
  
  
• All of the above figures are remarkable, given the racial disparities in socioeconomic status and education.
  
  
• In 1969, Louisiana had only 65 African-American elected officials. By 2001 (the most recent figures), the number had risen to over 700, including U.S. Rep. William Jefferson who is now among the most senior black members of Congress, having first been elected in 1990.
  
  
• As in other states �covered� by the preclearance provision of the Voting Rights Act, redistricting politics have been driven by the need to acquire Justice Department approval for all districting maps. Assuming that the state needed to create as many safe black congressional seats as possible, in the early 1990s the legislature designed an ungainly district that stretched more than 600 miles across the state. Several maps later, in the wake of Supreme Court decisions raising concern about such radical racial gerrymandering, that district was dismantled. Black candidates running in majority-white constituencies have not been successful, but the primary explanation seems to be the high proportion of whites who are Republicans and the weakness of those African-American office-seekers. For instance, in 2004, a black candidate for the U.S. Senate only garnered five percent of the black vote in the Democratic primary.
  
  
• Since 1993, blacks have held more than 20 percent of the seats in both the state House of Representatives and Senate. 
  
  
• In contested congressional elections in 1992 and 1994, in the second congressional district, which is almost 64 percent black, William Jefferson attracted approximately 90 percent of the African-American vote in the primary, but he also got just under half of the white vote, with the only white contestant receiving barely a quarter of the white vote. When blacks and whites differ in their candidate preferences, party affiliation appears to be a major factor. 
  
  
• There have been twenty-six primaries and runoffs since 1995 for statewide office, and in only two of the nineteen contested primary races have a majority of black voters lined up in opposition to a majority of white voters. In those nineteen contests, the candidate preferred by most blacks won, giving Democrats control of most statewide constitutional offices. Two politically important examples are the gubernatorial elections of 1991 and 2003.  In part, those outcomes reflect the fact that whites are less politically cohesive than blacks.
  
  
• Since 1996, Louisiana has had six primaries or runoffs for a U.S. Senate seat, and in every instance in which blacks cast a majority of their vote for a candidate, that candidate has prevailed. But the African-American vote is not always cohesive, and while, in 2004, a black candidate ran for the Senate, he polled only 5 percent of the black vote. The white vote is often split; moreover, when the majority of whites support a candidate, that candidate will often lose. 
  
  
• While roughly 30 percent of Louisiana�s registered electorate is African-American, black candidates are Democrats in a state in which George W. Bush won 75 percent of the white vote in 2004. Growing numbers of whites vote for Republicans. It is important to note, however, that Louisiana whites are not as consistently Republican as in some other southern states and several Democrats have attracted white-majority support.
