Abortion is a cultural issue, and which ever politician talks about Abortion for or against, is playing the classic textbook cultural partisanship game. Immigration is a bit complicated, but can be boiled down to both culture and economics. Clinton talks about tolerance(cultural), Trump talks about jobs(economics) being lost to immigration and open borders.

In my opinion Trump is not about 2016, but we will likely have a President in 2028 who runs on the Trump agenda of Native Populism, in a world of automation and globalization, his message is only going to get popular.
