The parish voters often supported Democratic presidential candidates before the 1970s, but the majority of white conservatives have trended Republican since that time.  Before 1965 and passage of the Voting Rights Act by Congress, most African Americans were disenfranchised, as they had been since 1898, when Louisiana passed a new constitution establishing barriers to voter registration and voting. They, along with poor white voters, were excluded from the political system. After regaining the power to register and vote, blacks tended to affiliate with and support national Democratic Party candidates.
The majority of the parish voted for the Republican Presidential candidates from 1992 to 2000, and did so by generally increasing margins. The results in 2004 gave Republican George W. Bush 64% of the vote and 57,732 votes while Democrat John F. Kerry won 35% of the vote and 31,210 votes. In the 2008 election Lafayette Parish cast the majority of its votes for Republican John McCain. He won 65% of the vote and 62,055 votes. Democrat Barack Obama was strongly supported by African Americans and won 34% of the vote, some 32,145 votes.
