Yes and no. I completely agree that what we see as Tucker is a character or farce, but he's going so far against the neocons that it has me confused. Who would fund him when he's attacks the largest party funders he somewhat used to relate to?
Actually I think that both are achievable concurrently. If the government would allow and encourage charitable organizations to provide care for immigrants then the welfare state would be dealt a fairly huge blow. No one in the government has the courage to attempt this however, because it would show the massive mismanagement of funds that the bureaucrats have been responsible for.
Having charity do more is a great idea. We have a lot of people who are already citizens, on welfare, they can start with. Then we can worry about accepting immigrants.
Carlson is just trying to disavow any traces of libertarian leanings he once claimed to have. Attacking the Koch Brothers is his way of saying "see I'm a populist just like Trump."
