Gallup has been looking at marriage rates for Democrats, Republicans, and Indepoendents since 1940. The two parties began to diverge in the early 1980s. Now the differences are striking.
Two thirds of Republicans are married whereas half of Democrats are not. And in this regard Independents most nearly resemble Democrats.
This finding makes sense in light of the relationship reported here that Republicans are happier than Democrats, and that married people are happier than the unmarried.
