What techniques did the democratic party use the gain power against the south?

In the era of  1990s, the Democratic Party made major attempts to court African American voters believing that the strength of religious values within the African American community. Unfortunately, it did not increase African American support for the Republican Party. Few of African Americans voted for George W. Bush and other national Republican candidates in the 2004 elections. although he got a higher percentage of black voters than had any GOP candidate.

Republican candidates mostly ignored black voters and even exploited racial tensions by the '70s and into the '80s and '90s.

Thomas Edge says that the election of President Barack Obama noticed a new type of Southern strategy emerge among conservative voters.

There are three most important points behind this diversion.

First, a nation that has the ability to elect a Black president is completely free of racism. Second, attempts to continue the remedies after the civil rights movement will only result in more racial discord, demagoguery, and racism against White Americans. Third, these tactics have been used side-by-side with the veiled racism and coded language of the original Southern Strategy.
