What the immigration raids are about

When you think about the current political fight over immigration enforcement, start with this: There are millions of people, at least 15 million and perhaps as many as 20 million, who are in the United States illegally. Millions of illegal migrants are new arrivals with no claim to stay in the U.S., having arrived in the mass border incursion of the Biden years. Many should be deported. But in our system, it is very hard to deport millions of people. It is easier to get them to deport themselves.
