Trump made it clear, but the left has  ignored, that the only Dreamers to be deported  are ones who are arrested and convicted of crimes in America.    Mexico's criminals and social detritus who run drug gangs and violent drug cartels in LA, San Diego, New Mexico, Nevada, and Texas will be the first to go. American jails are full already.  The Mexican hotel chamber maid working to feed her family  is a very low priority, unless she is caught stealing.
