Why don’t you read those two articles on academic studies on this issue I just provided here, FIH. You might learn something.
Based on my experience last Saturday on the street in two large neighborhoods just south of East Tropicana Ave in the “Paradise” and “Whitney” areas of your fine city, I believe LV also has quite a few illegal immigrants. Yes, hospitality workers have to furnish original documents for a Form I-9 to be hired. I get that. But they have parents up to 85 years old “hiding” in back bdrms. I don’t know how many of them are actually registered to vote, however. I believe they were brought to the US to take care of children and the home because these workers are subject to work any of three shifts (day, swing, or graveyard) and even back-to-back shifts (8 hrs apart) at the whim of their employer. We all know that LV is a 24-hour city.
I know this because I have a relative who retired from Sam’s Town and now has a union pension.
