Vox reports that there's been a stunning rise in the number of people who say they'd be displeased if their child married someone of the opposite party.
Nearly half of Republicans would be upset at having to include a Democrat around the table at Thanksgiving. (Of course if you want to avoid that, it's probably best not to reproduce.) Even a third of the more tolerant Democrats are likely to be unhappy about such cross-ideological breeding.
Meanwhile, Pew reports on marriage (a record number of Americans have never been married), showing that similar ideas about how to raise a child and having a steady job are more important than shared moral and religious beliefs. Religion is less important to the average unmarried man or woman when finding a spouse than politics is to the average Republican when it comes to finding a daughter or son-in-law.
Politics might be the new religion. For Republicans, in any case, a litmus test of belief in the workings of the invisible hand of the market seem nearly as important as faith in the invisible workings of more traditional spirits.
