Bernie and Trump were also both anti-war during the preliminaries, each for different reasons. I prefer Bernie's reason of defunding the military in order to put the money into more social benefiting areas, but Trump goal on focus more on internal US interests could have some of the same effects.
Yup. The idea that there's a single axis along which Bernie and trump is an incredibly simple-minded view of the world. Unfortunately, most voters are pretty simple-minded, which tells you a lot about why politics is the way it is.
The outcome naturally has a lot to desire.
