Minorities only like the Democratic Party because the Democratic Party panders to them and they believe in affirmative action instead of hiring a person based on their skill. The Republicans are not very popular with minorities because the Republicans don't pander to their every whim.
The Republican Party and its affiliates pander to a white, reactionary, right-wing base and stirs up those voters by portraying minorities in a bad light. There is a long history of this. There was Nixon's "Southern Strategy" in 1968. I remember how Bush I used Willie Horton ads against Michael Dukakis in 1988. And don't get me started at the various comments from the right about Sonia Sotomayor. Perhaps the lowest point was when an ad said she supported Puerto Rican terrorists. Jeff Sessions fanned these flames when he said that her affiliation with the Puerto Rican Legal Defense Fund made her "unsuitable for the bench" and claimed the group had taken "shocking" positions with regard to terrorism.
I take issue with the assumption that an affirmative action hire is less skilled than the supposed (white male) standard. Sotomayor has more experience as a federal judge than anyone currently serving on the S.C. did at the time of their nomination. Is she less qualified or "skilled" than Roberts or Alito?
As for the topic at hand, I am Asian and given their treatment of minorities over the years, I view the GOP with contempt.
