Bernie announces he is running again, what do you think?

I'm interested in what you Americans have to say about him. Do you want him to win the Democratic Primary and do you think he can? Are other candidates better? Is the age a factor?

I'm British so it's not my party to go to, though I do like what Sanders stands for and would definantely support him were I there. I think it's a shame that the rules prevent a 29-year-old from running as his VP though I hope AOC backs him and features in his campaign.
