I love this part:
"Not looking for an argument but this hits the nail on the head."
Of course she's not looking to start an argument, she never wins those unless she has a drink to throw in somebody's face or her sister Willow to back her up.
I would contend that this is actually one of Bristol's very rare attempts to make any kind of political point (The vast majority of posts posts on her blog are of course the work of Nancy French), and of course she screws it up by failing to recognize who Bernie Sanders is, and what he actually stands for.
I am sure that she saw this picture and in her pea brain thought "Yep, if I post this on Instagram people will know I am politically savvy, and have an informed opinion."
Instead of course it simply reinforces the fact that she is a barely coherent moron, whose only use in life seems to be drinking like a fish and trying to trap men into marrying her with her no longer under factory warranty vajajay and baby manufacturing uterus.
