His ‘concessions’ so far have only demonstrated that he isn’t serious about listening to leftwing voters
Joe Biden has a problem: the young people who fueled Bernie Sanders’ second-place campaign are not very interested in Joe Biden. Biden has a well-known enthusiasm gap and even though he has dominated recent primary states, younger voters tended to prefer Sanders or Elizabeth Warren. Progressive student groups around the country are declining to endorse Biden. A group of leftwing youth organizations sent an open letter to Biden demanding better policies if he wants their support.
On Monday, Sanders endorsed Biden, as he has long said he would. Alexandria Ocasio-Cortez has remained skeptical, saying that Biden needs to be made “uncomfortable” before there can be any kind of party unity. Many younger people share Ocasio-Cortez’s perspective; they are waiting to see what Biden can offer rather than reflexively supporting him because he is the Democrat.
