The only chance the republican party has is to appeal to American voters regardless of ethnicity.
The second they begin/began catering to differences in skin color, income level, etc they become/became cheap democrat imitations. And no one can out pander a democrat.
Which is exactly the mistake Jeb has made with predictable results.
That may be why Trump is winning so many blacks and Hispanics over to his side - because he doesn’t corral them off into minority groups. He just treats all Americans as Americans and appeals to them from that perspective. Which is the only perspective any of us should be concerned about at this point.
Oh and btw, Trump is polling somewhere around 25% among black people. That is quite an extraordinary accomplishment. But it’s not reported on the “news”.....
