Geographical Patterns in the Louisiana Republican Primary
As many commentators have noted, Santorum, a Roman Catholic, has done particularly well in areas dominated by evangelical Protestants. In the North and Midwest, Santorum have received more support from voters in this group than from Roman Catholics. In Louisiana, little difference is apparent between these two groups within the Republican electorate. As can been seen on these maps, the state’s striking division between its mostly Catholic south and its largely Protestant north was not reflected in this primary contest.
In the past, Louisiana’s religious divide was sometimes visible in election returns. The pattern was clearly evident in the general election of 1960s, in which John Kennedy, a Roman Catholic, triumphed in the south but lost the north.
