I just don’t think the article is reasonable. Clinton hasn’t gone right since her primary campaign, she has gone left, she was pulled left by the Sanders crowd. The examples from the article confirm that - e.g. She’s now on free tuition when during the campaign she seemed to think it was laughably unaffordable.
For the larger issue, I don’t have to make a choice about who to vote for for American president, so it’s not that pressing for me to sort this out. I think it can be reasonably argued that Clinton is a step in the right direction right now, or (hell, maybe even and) that voting for mass murder is impossible for a person of conscience to swallow, even if the alternative is also mass murder.
And if someone votes for Trump because they think he is less likely to wage wars, then I can even see how that could be a sensible if heart-rending decision (even as I think they are dead wrong).
But yeah, if Clinton wins and in 8 years are choosing between someone who wants to reverse the suffrage from the Republicans and someone who literally has, “Fuck you, you have to vote for me” tattooed on their forehead, we’ll all know why.
