“80-20” issues have become a catchphrase recently. Most voters on those issues favor one policy by overwhelming margins and oppose the other. The “winning side” may poll anywhere between 60 and 90 percent, depending on the issue, but they are all conveniently grouped under the same label of “80-20.”
These lopsided issues have three striking features. First, there seem to be more and more of them, especially on contentious social issues and law enforcement. Second, the same constituency that supports the 20 percent side of one issue frequently supports the 20 percent side of other issues, even those that are substantively quite different. Once an issue is depicted as “progressive,” for example, it generates that support. The result is that a series of issues have overlapping support, forming a coalition. Third, although elected officials (and candidates for office) might be expected to shy away from supporting issues with only 20 percent support, today’s Democrats have actually backed most of them. Support has been most vocal from the party’s progressive (far-left) wing, but center-left Democrats have rarely opposed them, at least openly. In a party that has gradually moved leftward, even moderates are wary of being caught opposing progressives. The rare exceptions come in “purple” states and congressional districts (that is, districts where the general electorate could vote either Democrat or Republican).
The easiest way to see how these leftist support groups overlap on multiple issues is to ask yourself, “Do you think the people who oppose closing the Southern border also oppose Israel?” The answer is obvious. They do. Support for open borders strongly predicts opposition to Israel.
Once I know someone supports open borders and opposes Israel, it’s not hard to predict her position on transgender women in men’s sports or school choice. Although those issues are strikingly different substantively, a voter taking the 20 percent position on one of them is very likely to take the 20 percent position on the others. The result is an activist progressive coalition that encompasses all these issues and more.
