Your premise assumes that a given voter believes that the relatively far-left economically populist policy prescriptions espoused are A) feasible and executable, and B) necessarily in their interests.
I guess this is what they mean when people say that Reaganomics has tricked poor people into thinking they aren't actually poor and could feasibly "get rich with enough drive" to vote against themselves.
That's the exact mindset we have to confront in this election.
And your assumption is that Bernie Sanders is in the best interests of more than half of voting Americans. Which may be true. I dunno. It's a big assumption, though. And, I do know that people act against their best interests all the time.
This is also true, but it doesn't mean its right.
You can say your for your medicare and medicaid benefits,
Your social security pension,
For more money when you have a low paying job in the service industry you can barely hold onto,
For more of a fair shot when you have to pay a bazillion dollars in insurance to private health corps,
For more of a break when you have to pay shitloads in prescription drugs or go across the border,
For some respite when you loose all your livelihood to student debt barely getting loans when going to college,
For some mercy from god when your entire life is gambled away in a global ponzi scheme of speculative banking derivatives totally not your fault,
But it doesn't matter if someone can sell you the possibility of being rich sometime in the future and America and freedom even if its just words.
So its a pretty messed up situation, as certain people who are trying to argue
No I'm saying he's too far left because he's too far left. Again, you can't take 'popular opinion' as saying he has majority appeal across party lines. The last 3 elections have seen roughly only 58-60% of all eligible voters turn out, of which Republicans get roughly half the popular vote. The 2012 and 2004 elections were pretty close in terms of popular vote numbers. But GOP has roughly gotten 60 million votes each election.
And so in general, voter turnout must be addressed. That has nothing to do with his policies. Voter turn out in the independent and left leaning sides is so low because we have situations like this, in which people are demoralized because nothing changes in Washington. Why is congress hated so much? Because of that. Now we have someone who really has a broad platform for systemic changes to our issues, who would not vote for that, once they actually heard about that possibility?
Now you take Sanders, someone who has long been called a socialist, who is Jewish but almost atheist from New York, he's anti-gun, not religious, pro-choice, pro-immigration reform and amnesty, pro-environment, anti-oil/anti-pipeline, pro-LGBT, pro-obamacare/universal Healthcare etc. He's a complete nonstarter for almost every single red/conservative state and when the campaign dollars are flying, he's going to get roasted for these choices. If that means common sense is dead, then yeah probably. Wait until the oil companies, rich conservative donors, military industrial complex start taking out attack ads. Unlike Obama who was a charismatic speaker who capitalized on change we can believe in, you're facing a Republican majority in the Senate and house. Hillary Clinton has far broader appeal. Just look at how many voters Obama lost to Romney in 2012 versus McCain in 2008. Then again, what do I know. All I fear is more of the same in the US. Even a guy like Obama who wasn't really entrenched with corporate interests, who wasn't a career politician, is himself a minority wasn't able to achieve much, what could a president really do these days?
I can tell you this: voting for Hillary REALLY isn't going to change anything. If what your scared about is the status quo, that is the same thing as voting as her based on her allegiances to Citibank, JP Morgan Chase and Goldman Sachs over you, and she will switch any position made during this campaign when 'circumstances become too hard' in the White House.
We should be arguing from a position of strength. People always talk about compromise. Its better to be compromising with the opposition starting on the assumption that the person we have on our side is actually genuinely fighting for our own causes, actually fighting earnestly instead of making a business transaction in the wrong way.
Hillary starts on their side from the start.
