the option of voting abroad OR in MD, my US voting residence and actual part-time physical residence, I would just like to point out that there are actually several like me who may deliberately have chosen to vote absentee ballots from their voting residence instead of in the DA Global Primary. Of those, several are like me and would have voted for Hillary. Others would likely have voted for Bernie.
Also, of those who voted in the DA primary (there is NO Republican global primary), many were likely also Republicans who signed up as Democrats to vote and others may have been "independents" who voted. It is likely that both of those groups voted for Bernie.
I know that where I would have physically voted had I not chosen to vote in MD (Geneva, Switzerland), the actual vote talley was very close to even, although Sanders had a slight edge. In Geneva, we who are longtime Dems KNOW each other personally and thus it is very likely that there were fewer Republicans or independents (having become latter-day Dems solely for purposes of this primary) to skew the results.
It is true that those of us who live in countries where the government plays a large and generally effective role in managing health care, education, social benefits and transportation, among other things, generally love the quality of life in those countries. This experience may have affected some who genuinely voted FOR Bernie as opposed to being spoilers for Hillary.
But it is also true that those of us who are longtime Democrats view warily someone who only became a "Democrat" after years of refusing to do so and after years of criticizing the party. We may like him and what he says. But we have no basis to trust someone who has shown little institutional loyalty and who has only ever had to deal primarily with people who look and think like him.
My point here is: it is literally impossible to draw ANY conclusions whatsoever from the DA Global Primary outcome. Each person's experience is unique to that person. Period. That is all. Bernie won the primary and nine delegates. Congratulations to him! But please do not take this to mean in any way, shape, or form that "the world" wants Bernie Sanders.
