Look at the counties Ted Cruz won in Michigan. Six of them are clustered on the western edge of the state, the part that includes Grand Rapids and Holland. That cluster contains the only five counties — Newaygo, Oceana, Ottawa, Allegan and Kent — where Cruz won more than 35 percent of the vote.

They’re also the most Dutch parts of the state. Allegan is 20.8 percent Dutch, Newaygo is 13.3 percent Dutch, Kent is 18.6 percent Dutch and Ottawa County (home to Holland, Michigan) is 30.4 percent Dutch and also gave Cruz his largest margin of victory of any county: 16 points over John Kasich and 20 points over Trump.
