I actually think Bernie would have lost. Interesting thought exercise though.
There's a fair amount of states who voted for Sanders and Trump: idaho, montana, north dakota, wisconsin, west virginia, oklahoma, kansas, nebraska - lots of these states were close races in the general, it's not hard to think that sanders would have won there since he was actually trying to address their core issue of middle class jobs. And it shows that at least the democrats in those states preferred Sanders to Clinton.
The states that voted for Sanders and Clinton: washington, oregon, colorado, minnesota, lots of new england states - basically all the guaranteed blue states no matter who the candidate is.
I think:
- Primary voting is suggestive of turnout, but when you've got a candidate that people are voting against out of hate, it is hard to infer true support. So, I don't know if Bernie would have won.
- I heard (unconfirmed) that 9% of registered democrats voted for Trump. Such a weird section that, again, it is hard to infer support.
- It is all moot now anyways.
Ideally, Bernie's platform would offset the cost of some free higher education by closing corporate tax loopholes, releasing non-violent drug offenders from tax-funded prisons and jails, and significantly reducing military spending.
