MICHAEL BARONE: Ethnic Politics: The Dutch-Cuban Alliance. “Some years ago I made the observation that the most Republican ethnic groups were Dutch- and Cuban-Americans. But, I added, it seemed unlikely that they would ever get together. Wrong. In this year’s Republican primaries and caucuses, the Cuban-American Ted Cruz has run extremely well in counties with large Dutch-American populations. You could almost say there was some kind of affinity there. You can see it in the election returns, looking at communities with high percentages of Dutch ancestry and counties where 7.6 percent or more of residents identified themselves to the Census Bureau as having Dutch ancestry.” Interesting, though I doubt you can sweep the nation with that particular mix.
