Where does this idea come from that Democrats want unrestricted immigration? Obama deported more illegal immigrants than any other president ever and stopped awarding new visas from the same countries that Trump's executive order applied to. He just didn't do crazy/potentially illegal like Trump is doing or has suggested doing like indiscriminately turning away green card holders or using the National Guard to round-up millions of illegal immigrants.
