An online debate over foreign workers in tech shows tensions in Trump's political coalition

An online spat between factions of Donald Trump’s supporters over immigration and the tech industry has thrown internal divisions in the president-elect’s political movement into public display. The argument previews fissures and contradictory views his coalition could bring to the White House. The rift laid bare tensions between the newest flank of Trump’s movement — that is, wealthy members of the tech world who want more highly skilled workers in their industry — and people in Trump’s Make America Great Again base who championed his hardline immigration policies.
