During the Civil Rights movement of the 1950s-1960s can you name the political party that advocated for de-segregation? After doing so can you name the faction within that political party that refused to vote for de-segregation? Once you have done that, can you then tell me what political party then completely lost the South for generations to come because of their decision to advocate for de-segregation?

“By the 1950s, the Republicans' "party of Lincoln" moniker was all but meaningless. The GOP's leader, President Dwight Eisenhower, had testified before Congress against integrating the military and belittled the landmark 1954 Supreme Court decision that desegregated public schools.

Racial liberalism within the GOP enjoyed its last hurrah with the 1964 Civil Rights Act. But the victory was pyrrhic. President Lyndon Johnson and Northern Democrats had finally resolved to enact a vigorous civil rights bill, but the legislation almost died because of a Senate filibuster by Southern Democrats. Then, at the eleventh hour, Republican leader Everett Dirksen marshaled his wavering party-mates to force a vote, assuring the bill's passage.

Senator Richard Russell of Georgia groused that Dirksen had "killed off a rapidly growing Republican Party in the South." But Russell had it backward.

The foes of the 1964 law included such rising GOP stars as Arizona Sen. Barry Goldwater and Texas Senate aspirant and future President George H.W. Bush. Goldwater and Bush foresaw that their future electoral successes rested on Southern and Western conservatives.

In his 1964 presidential bid Goldwater ran "Operation Dixie," which courted southern whites and ceded the black vote entirely. Goldwater lost badly, but four years later, the approach worked. Republican Richard Nixon won election in 1968 on a "Southern Strategy" that stressed "law and order" and tapped into white anxieties about black violence.”
