From the 2016 Cooperative Congressional Election Study, positions of primary voters on five immigration issues:
Note that primary supporters of “Another Democrat” (whatever became of Jim Webb?) were more hawkish on every question than John Kasich’s primary voters. Several of those endangered Blue Dogs crossed over to Trump’s GOP. The Ohio governor has a speaking spot at next week’s Democratic National Convention. The realignment continues.
Parenthetically, the idea that many Sanders supporters were “based” on immigration is a restrictionist fantasy. It wasn’t true in 2016 and it’s even less true now.
