In his successful 1980 campaign against Jimmy Carter, Ronald Reagan won about half of the Catholic vote and a majority of Catholics who were non-Hispanic whites. "Reagan Democrats", many of them non-Hispanic white, blue-collar Catholics, comprised 25% of the Democrats who voted for Reagan, and formed an important part of his support in 1984 as well. Despite Catholic Geraldine Ferraro's presence on the Democratic ticket as Walter Mondale's vice-presidential running mate that year Reagan won 54 to 61% of the Catholic vote, only slightly different from the overall 59%. Although the majority of Catholics in 1984 remained Democrats, compared to 1980 Catholic votes switched to Reagan at about the same level as most Protestant groups. Reagan's vice president George H. W. Bush won about the same number of votes as Michael Dukakis, making 1988 the third presidential election in a row in which Catholics failed to support the Democratic candidate as they traditionally did.
