You start out in 1954 by saying, “Nigger, nigger, nigger.” By 1968 you can't say “nigger” — that hurts you. Backfires. So you say stuff like forced busing, states' rights and all that stuff. You're getting so abstract now [that] you're talking about cutting taxes, and all these things you're talking about are totally economic things and a byproduct of them is [that] blacks get hurt worse than whites. And subconsciously maybe that is part of it. I'm not saying that. But I'm saying that if it is getting that abstract, and that coded, that we are doing away with the racial problem one way or the other. You follow me — because obviously sitting around saying, “We want to cut this,” is much more abstract than even the busing thing, and a hell of a lot more abstract than “Nigger, nigger.”

“With regards to the young people, for instance, a forgiveness of college loan interest was a big gift,” Mr. Romney said. “Free contraceptives were very big with young, college-aged women. And then, finally, Obamacare also made a difference for them, because as you know, anybody now 26 years of age and younger was now going to be part of their parents’ plan, and that was a big gift to young people. They turned out in large numbers, a larger share in this election even than in 2008.”

The president’s health care plan, he said, was also a useful tool in mobilizing black and Hispanic voters. Though Mr. Romney won the white vote with 59 percent, according to exit polls, minorities coalesced around the president in overwhelming numbers: 93 percent of blacks and 71 percent of Hispanics.

“You can imagine for somebody making $25,000 or $30,000 or $35,000 a year, being told you’re now going to get free health care, particularly if you don’t have it, getting free health care worth, what, $10,000 per family, in perpetuity — I mean, this is huge,” Mr. Romney said. “Likewise with Hispanic voters, free health care was a big plus. But in addition with regards to Hispanic voters, the amnesty for children of illegals, the so-called Dream Act kids, was a huge plus for that voting group.”
