Because, ew?

Biggest ever family tree shows when cousins stopped having sex

...It was thought that people in the west stopped marrying their close relatives in the 19th century, because improved transport meant that people were born further away from their families. But the family tree proved otherwise.

"Even though people started to be born further away from their families during the early 19th century, they were still marrying cousins for 50 years," says Kaplanis. It seems the eventual decrease in inbreeding was more to do with cultural influences. "It just became less socially acceptable."...

It's legal in the UK and it's said that first-cousin marriages increase the risk of congenital defects to 4% from a norm of 2%. It's also said that 4% is the rate for over-40 mothers (and there's absolutely no way that those ladies could be legislated against without precipitating another Civil War). A growing problem, however, may lie in our historic immigrant populations, particularly those of Pakistani origin, in which first-cousin marriages are encouraged. Generation after generation of that possibly (probably?) increases the risk factor substantially - but I can't find any data for that (not surprising, given the subject matter would raise all kinds of accusations of racism). But we can't have two laws, so it's either in or out and, as there has been no apparent spike of cousin/cousin oddity in the data, it's got to be in.
Besides, we have to get our politicians somehow,

Some of my cousins say "Don't leave the county for a wife." Half-joking, half-serious. To put up with their brand of tribalism I guess you have to be born into it.

In Kentucky and Alabama, strike that. In most of the South, and parts of Boston and New Jersey they say "Don't leave the county for a wifey."

The fact that trump wants to {!#%@} his daughter is why he appealed to southern men. They can relate.
