This is an article about the Republican Party. Students of U. S. History know that the Abraham Lincoln led Republican Party came to be the party of abolition and emancipation, as a result of this and the Civil War, the Democratic Party became, for all practical purposes, the only meaningful political party in the South. This situation continued through the Roosevelt New Deal coalition years, with the first break in this coalition coming with Truman's desegregation of the armed forces, and the Dixiecrat walkout of the 1948 Democratic Convention.
When Lyndon B. Johnson signed the Civil Rights Act of 1964 he said the Democrats would lose the South for generations, he was correct, the rest is history. NIxon was the first Republican to play the race card and use this Southern strategy, it has been successful ever since. Some posters write as though Democratic racism, especially in the South is a revelation, a shock. The Democratic Party in the South is not the Democratic Party.
It was Democratic Attorney General Nicholas di Katzenbach who faced Democrat George Wallace at the schoolhouse door, the school was desegregated, the rest is history.
I wrote this for the record. The Democratic Party has been a disaster since Carter, but mainly Clinton, it is for all practical purposes, social issues excepted, a clone of the Republican Party. Bernie is running, for practical purposes, and to get his message out, under its label, Go Bernie.
I must add an addendum: President Dwight David Eisenhower (The last of the non southern strategy GOP presidents) nationalized the Arkansas National Guard to force integration of Little Rock's Central High School in 1957, an important step in the Civil Rights Movement:
Correction: Katzenbach was Deputy Attorney General, not Attorney General.
