But that applies even more in NH—and they’re not falling for him.
Having been to both states, I think New Hampshire has more awareness of blacks due to its proximity to Boston. The media influence from that city exposes southern New Hampshire to the unceasing wave of black crime and its ghetto "culture". In contrast, Iowa is relatively isolated in that regard.
Clueless colleagues of mine in the upper midwest perceive blacks as "spice" in their otherwise largely white demographics. And when blacks constitute less than 10% if the population, they do tend to be better behaved. It's a fact that the first black on a white street assimilates pretty well. But a tipping point occurs when more of them move in and the ghetto "values" start to hold sway.
