There is very little doubt about the modern GOPs' relentless appeal to racists.
As the Southern Strategy became apparent, fewer and fewer African-Americans voted Republican in the last 4 decades of the 20th Century.
Republicans saw an opportunity to gain votes by appealing to racists who never forgave the Democratic Party for supporting civil rights.
Many charges of racism have been made regarding recent Republican campaign tactics.
The infamous Willie Horton commercials used by George H. W. Bush against Michael Dukakis were racist.
The 1990 campaign of Jesse Helms attacked his opponent's alleged support of "racial quotas," most notably through a notorious TV spot in which white hands were seen crumpling a letter (stating that he was denied a job because he was Caucasian), was likewise racist.
The Republican Party went too far when they stole the 2000 and 2004 presidential elections.
Once Barack Obama became the Democratic challenger to GOP racism, the Republican strategy of appealing to racists through "codewords" was rendered ineffective.
Obama gained majority support in Virginia, the District of Columbia, Maryland, Florida, Delaware, and North Carolina, and he also won southwestern states that had previously voted Republican.
