I am beginning to suspect that one of Tucker Carlson's primary motivations is finding spouses for his kids. He has four kids, three daughters and one son. He had them quite young so they are either soon reaching or are at the age when they would normally look for lifelong spouses.
While Tucker is wealthy (he is an heir to the Swanson fortune and lives in a NW DC neighborhood where I doubt that the normal salary of a Fox anchor would allow him to live with a wife and four kids), I think that he is discovering that all of the money in the world is not going to help him become a father-in-law and grandfather in today's society, especially Washington, DC's.
If they stay in DC, his three daughters are going to be courted either by soy boy leftists or vicious power hungry sociopaths who consider Bill Clinton a roll model. Men who be able to attract them and then commit to them to become good husbands and fathers are in very short supply inside the Beltway, even with the help of a family trust fund.
As for his son, this site once upon a time thoroughly documented the struggles that he will have finding a good wife in the DC area, regardless of money.
While his kids could move, Tucker and his wife would probably want them around so that they could help raise any grandchildren. Tucker, at least a few years ago, often discussed that being able to move anywhere in America has a real downside since it rips you away from your extended family and community.
My guess is that this is what weights heaviest on his heart.
