Blacks and latinos in general are never going to vote Republican because they consistently reside at the lowest ends of the socio-economic spectrum and want the maximum of government assistance. They’re never going to move up the spectrum because of low average IQs (85 and 90 respectively in the USA).
The following idea is nonsense: “That complexity of opinion is one reason why Republican strategists hope that with the right candidate — and a little bit of luck — they can reverse the pattern of Latinos voting overwhelmingly for Democrats. In New Mexico, where Latinos make up more than 40% of voters — more than any other state — Latino Republicans have made considerable gains, even though the state voted for President Obama in the last two elections.”
