Don't know of many black Latinos (Obama got 71 per cent) or black Asians, which in the US means oriental as well as Indian etc, (73 per cent)!
But there's more to it than that. He got 60 per cent of voters aged 18 to 29 and 52 per cent of those 29 to 44.He got 59 per cent of all women, performing particularly well with young, single, women, 62 per cent of those voters who never attend religious services and 55 per cent of those who attend occasionally, and 60 per cent of those earning less than $50k a year.
That's a very broad appeal, which Romney could not match. Obama scored because of voter empathy, that people thought he cared for them as individuals. A candidate who dismisses 47 per cent of the electorate as thinking themselves victims or who tries to be an Ordinary Joe for them by saying that he was interested in NASCAR as some of his friends own NASCAR teams, is never going to be thought able to identify with them
All that
