WAS THERE A BIDEN BOUNCE? Kind of, a new @CBSNewsPoll finds. Heading in, many of @JoeBiden’s backers were with him predominantly to oppose President Trump. Now, relatively more Democrats are backing Biden because they’re for Biden: that percent is changed by nine points. https://t.co/cGMaW4cwlP — PolitiTweet.org
