Business Insider takes a look at eight political dynasties (unfortunately it calls them the “New Kennedys”). Among them are the Romneys and the Udalls. I keep forgetting that Mike Lee is included among the Udalls along with former-Senator Gordon Smith and cousins Senators Mark and Tom Udall. Interesting how a party split followed family lines.

Patriarch David King Udall, a Mormon polygamist, had 12 kids, six with each of his two wives. The descendants of his wife Eliza have been Democrats, and descendants of his wife Ida have been Republicans.
