By simply checking common minority names and NOT using the last 4 digits of their SSN to distinguish between different people with the same name the GOP are able to suppress the votes of millions of minorities. The U.S. Census data shows that minorities are overrepresented in 85 of 100 of the most common last names. If your name is Washington, there's an 89 percent chance you're African-American. If your last name is Hernandez, there's a 94 percent chance you're Hispanic. If your name is Kim, there's a 95 percent chance you're Asian. Blacks vote 90% Democratic, Asians 75% Democratic and Latinos 67% Democratic, so the GOP realized that the more minorities they can suppress the better their chances of stealing an election.
Are you saying that names such as Smith, Jones, Brown are not being checked? You also left out the fact that the middle name is used along with the birth date.
Your desperation is duly noted!
