What "looks like America"?

Hillary is mopping up the floor with Bernie because 22 % of Democrats, making up nearly 60 % of party voters in South Carolina and expected to show up in numbers like that in much of the Super Tuesday region, prefer her by close to 90 %.

An enthused campaign spokesman on MSNBC less than half an hour ago cited these numbers and explained that the Hillary campaign had been confident all along that she would do well once the contest moved to states that look like America.

As for today, her people are working hard to get out the vote among blacks, Hispanics, and others representing America's diversity, he said.

The CIA World Factbook says of the US,

Ethnic groups:

White 79.96%, black 12.85%, Asian 4.43%, Amerindian and Alaska native 0.97%, native Hawaiian and other Pacific islander 0.18%, two or more races 1.61% (July 2007 estimate)

Note: a separate listing for Hispanic is not included because the US Census Bureau considers Hispanic to mean persons of Spanish/Hispanic/Latino origin including those of Mexican, Cuban, Puerto Rican, Dominican Republic, Spanish, and Central or South American origin living in the US who may be of any race or ethnic group (white, black, Asian, etc.); about 15.1% of the total US population is Hispanic.

Wikipedia reports the 2010 census interestingly showing a bit fewer whites, blacks, and other individual named races but sharply more people in the category for multiracial/some other race.

Race/Ethnicity (2010 census)
By race:
White American 72.41%
African American 12.61%
Multiracial and Some other race 9.11%
Asian American 4.75%
American Indian and Alaska Native 0.95%
Native Hawaiian and Pacific Islander 0.17%
By ethnicity:
Hispanic/Latino (of any race) 17.4%
Non-Hispanic/Latino (of any race) 82.6%

Wikipedia says of Iowa,

According to the 2010 Census, 91.3% of the population was White (88.7% non-Hispanic white), 2.9% was Black or African American, 0.4% American Indian and Alaska Native, 1.7% Asian, 0.1% Native Hawaiian and other Pacific Islander, 1.8% from two or more races. 5.0% of the total population was of Hispanic or Latino origin (they may be of any race).

And it says of South Carolina,

As of the 2013 census estimate, the racial make up of the state is 68.3% White (63.9% non-Hispanic white), 27.9% Black or African American, 0.5% American Indian and Alaska Native, 1.5% Asian, 0.1% Native Hawaiian and other Pacific Islander, 1.7% from two or more races. 5.3% of the total population was of Hispanic or Latino origin (they may be of any race).

Neither is dead on, but which state looks more like America?

Actually, SC does seem closer, overall.

Iowa really is too white.

Gallup a few years ago said the GOP is 89 % non-Hispanic white, 2 % black and 6 % Hispanic.

That makes the GOP notably whiter than the whole population, less black, and less Hispanic, and an excellent match for Iowa.

Democrats, it said, are 60 % non-Hispanic white, 22 % black and 16% Hispanic.

That makes the Democrats less white and notably blacker than America, and a fair match with South Carolina.

Actually, it seems that the Democrats would be dead on to look like America were it not that they enjoy overwhelming popularity among blacks, compared to the GOP.

That over-representation of blacks in the party pushes down the white share of the total.

Similarly, that preference for the Dems by American blacks as well as Hispanics drains the GOP of color, leaving it overly white.

Of the GOP it is always well to ask why anybody at all, not absolutely rolling in dough, is a Republican.

The answer is not that so large a number of people are selfish plutocrats or knowing servants of same.

It is that the disproportionate volubility among Democrats of people who hate whites, white men, Christians, capitalism, and even Western Civilization entirely has alienated and terrified many whites, driving them into the open arms of their class enemies.

And others have crossed party lines who believe they have been profoundly hurt economically by mass low-wage immigration both legal and not and by free trade in a global economy that has given their jobs to foreign workers who live like slaves.

Democrats offer no help but the GOP does have a protectionist and anti-immigration wing.

But so many are these people and so little interested are they in the Wall Street agenda that they have very nearly taken over the party and are very close to naming their own man as the GOP nominee for the presidency, to the despair and outrage of the flunkies of Wall Street and the emerging global plutocracy who have dominated the party since Reagan and who got such a swell boost out of the collapse of the Soviet empire.
