All of the polls are currently showing that Biden can beat Trump. It's not rocket science, it's obvious who we should nominate if we want to beat Trump. The other front runners are either tied with Trump, within the margin of error, or losing to him. Either we want to go with the surest most moderate, electable candidate available or we want to take a higher risk with one of the more progressive candidates. Biden has a long political history that spans over many eras and he has old stereotypes and prejudices embeded in his brain at a subconscious level. But I don't believe that he would act negatively based on those blind spots and I believe that he is open minded enough to allow others around him to correct him when necessary. He even quickly corrected himself when he realized within seconds that his statement was based on an incorrect stereotype. But, Trump is an intentionally blatantly racist person who will actively seek to hurt anyone or anything that gets in his way while dividing this country at a level that I've never seen in my lifetime. Weakening the potential democratic nominee will only hurt us in the end. It's bad enough that Russia will most likely try to push the racist narrative on Biden but now we have fellow Democrats doing their work for them. This was very irresponsible on Rihanna's part in my opinion.
