Every time I find a way to say that there is no one like Bernie Sanders, there are people who don’t believe me. Aren’t there other candidates who support the same policies he supports now? Some of them are younger. Some of them aren’t old white guys. Why can’t it be one of them, why can’t it be someone new? Over and over, I have tried to find ways to explain that there is a real difference between Bernie Sanders and everyone else. Today, as Sanders announces his candidacy for the presidency, I’m going to try one more time.
