A few months ago I got into an argument with someone about the media saying that Trump was going to do well because he was focusing on Working Class Voters. The thing is, while Ronald Reagan did well and even won due to Working Class Voters at the time, there are a whole lot less of them today than there were back then. Since Reagan took office, the Service Sector has grown while the traditional Working Class have shrunk. There’s fewer people employed in manufacturing, mining, and the like today than there were in 1980. Add the racial factor into this, and you cut into the Working Class Voter numbers, and the same holds true for all the other minority categories.
Basically, Trump is going to lose because he’s trying to appeal to the one group which is pretty rare these days.
