Of course Sanders had a choice especially given the fact that Sanders had proclaimed that he was going to start a “political revolution” which certainly was not going to happen when he supported not one but two corporate Wall Street hacks, namely Hillary Clinton and Joe Biden. In 2016 Sanders correctly pointed out that H. Clinton was not qualified to be president but yet he chose to support her. He does the same thing in 2020 when he once again betrays his followers by supporting a person who shared very few of his beliefs. It should also be pointed out that Biden does not support one of Sanders’ main ideologies and that would be a form of universal health care. Sanders does a wonderful job of placing party over principle.
As the late comic George Carlin once observed, this is the best that America has to offer and do not expect it to get any better. As for Sanders when the Savage Mules tell Sanders to jump he replies: How high?
