Are the far right Christians here in the U.S. just upset they're losing power

In American politics, the Southern strategy refers to a strategy by Republican Party candidates of gaining political support in the Southern United States by appealing to disaffected white southerners, many of whom were originally Democratic voters.

During the 1950s and 1960s, the African-American Civil Rights Movement achieved significant progress in its push for desegregation in the Southern United States. The Civil Rights Act of 1964 and the Voting Rights Act of 1965, in particular, largely dismantled the system of Jim Crow laws that had enforced legal (or de jure) segregation in the South since the end of the Reconstruction Era. During this period, Republican politicians such as Presidential candidate Richard Nixon worked to attract southern white conservative voters, most of whom had traditionally supported the Democratic Party, to the Republican Party,[1] and Senator Barry Goldwater won the five formerly Confederate states of the Deep South (Alabama, Georgia, Louisiana, Mississippi, and South Carolina) in the 1964 presidential election. In the 1968 presidential campaign, Nixon won Florida, South Carolina, North Carolina, Virginia, and Tennessee, all former Confederate states, contributing to the electoral realignment that saw many white, southern voters shift allegiance from the Democratic Party to the Republican Party during this period.
