Sure thing. People can make up a lot of explanations to make things sound plausible.
Romney got 6% of the African-American vote, against Obama’s 93%, and 27% of the Hispanic vote, against Obama’s 71%. McCain got 4% of the African-American vote, to Obama’s 95%, and 31% of the Hispanic vote, to Obama’s 67%. In 2004, Bush got a whopping 11% of the African-American vote, to Kerry’s 88% , and 44% of the Hispanic vote, to Kerry’s 53%. In 2000, Bush got 9% of the African-American vote, to Gore’s 90%, and 35% of the Hispanic vote to Gore’s 62%. Looking back to 1996, Dole got 12% of the African-American vote to Clinton’s 84%, and 21% of the Hispanic vote to Clinton’s 73%.
Trump got 8% of the African-American vote, to Clinton’s 89%, and 28% of the Hispanic vote, to Clinton’s 66%.
Trump
currently has a 36% approval rating among African Americans. It’s also interesting that, when Black unemployment is at its lowest point evahhh since they started breaking it down by race in the 1970’s-- it’s never dropped below 6% before-- there’s still 64 African Americans out of every 100 who disapprove of the job being done.

(It was 16.5% Black unemployment in Jan 2010. It was 10.4% Black unemployment in Jan 2015.)
I got bored after I went back 6 elections (24 years) and only found two instances where the Republicans actually got double-digit support from the African-American voters. Something is interesting when, out of a group, you more than 9 people voting D for every 1 person voting R. Hispanics aren’t quite that lopsided— but in general, for every Hispanic who votes R, you have two or three who are voting D.
For someone who got twice the Black vote that McCain did— and a bit more than Romney-- “but, but, but the minority appeal!” is not a very compelling argument.
