Welcome to their nightmare. When President Trump delayed repealing DACA, some saw the grace period as compassionate. But to many immigrant advocates, it pits children against the parents who brought them to the U.S. Under the DREAM Act, so-called “dreamers” had to tell the government where they lived, so they’re vulnerable and may accept tougher enforcement against other undocumented immigrants — often their parents — as the price of a reprieve. Advocates have pledged solidarity, but when a deal must be struck, the pressure for self-preservation may be too great to resist.
