Maybe some people are supporting Trump purely for his tougher sounding immigration stance. Some folks I spoke to know co-workers say that they are supporting Trump because they work in hospitals and am sick of all the free healthcare and lack of gratitude from illegals.
At the end of the day, I’m guessing a lot of these people just don’t care as much about all the other downsides of a Trump presidency, but want to shut down the thing that affects them the most.
