You'd be surprised at how many of these "illegals" have papers. I've worked in kitchens, and restaurants with entirely Hispanic staff (including me) and a lot of them had various resident visas while they waited for their green cards (which takes a few years to get) in my time working with these guys I only ever saw one person get deported, and he was back in Texas in 2 weeks. After spending 2 weeks in Cozumel on the beach, he hopped a flight into Austin, and walked out of the airport like nothing.
Fat lot of good deportation does.
In all seriousness this trump dude is a complete loon, with no political background or experience that has polarized his own party massively. I hope he don't win shit.
