Another Inevitable Result of the Great Inversion

So one thing that's making the rounds today is a poll showing an ever-increasing number of people saying they wouldn't like it if their child married someone of the opposite political party. This of course shows how terrible Americans are, how acrimonious our partisan divides, how tribal our politics, etc. Because you see, in 1960, 4% of Democrats and 5% of Republicans said this. In 2008 it was 20% of Democrats and 27% of Republicans. Now it's 33% of Democrats and a whopping 49% of Republicans. People are becoming that much more ideologically intolerant, I guess.

Or not. We don't know how ideologically intolerant people were in 1960. Not from this survey data at least. Because, as I detailed in my previous post, back in 1960 party identification correlated only weakly with ideology. More to the point, there was a considerable amount of ideological overlap between the two parties. A Democrat and a Republican from Massachusetts had an awful lot more in common with each other than that Democrat would have with a Democrat from South Carolina. Indeed, it's quite likely that, at least if you go back a little further, the Massachusetts Democrat would have had more in common with the South Carolina Republican than with his southern co-partisan.

So if you had the strong feeling that you didn't want your son or daughter marrying someone whose ideology you found hateful, it just wouldn't make a lot of sense therefore to decide you didn't want them marrying someone of the opposite party. You would presumably want to be discriminating among cross-partisans, just as you would need to be discriminating among co-partisans. These days, though, if someone puts an R after their name it gives me a pretty good idea of what they're all about, or at least what they're willing to tolerate. So whether you like the practice or not, it just plain makes a lot more sense to disfavor members of the opposite party, for your children or for yourself.
