Are Sanders supporters realistic and involved enough to realize what will happen if they do not support Hillary?
Yes what you're saying is simply "vote Democrat" since this is still better than the real evil.
However, the problem is, many including me don't see much "democrat" when we look at Clinton. She could WELL be over at the Rep side, would much better represent actual "Republicans".
SHE represents "normal" Republicans much more than anything, the current so called "Republicans" are way, way too much to the right.
Go look at Clinton's policies. She made it clear she's against $15 MW, free tuition, she's establishment, gets stuffed by Wallstreet and basically everything I'd associate with an actual Republican.
So, just voting for her "because she is [allegedly] Democrat?" doesn't make sense seeing she really ain't one...that's how I see it.
So...even a Trump presidency is not THAT much worse in comparison....with Trump having the "advantage" he is anti-establishment. Like Bernie, just 180 degree opposite of course.
