A shame Booker cannot connect more, he should have a real chance, but unfortunately, I don't think he does. Warren may just be the one, Biden a close second. Castro showed his over eagerness and immaturity. I don't think Harris has the experience for the national stage yet, but I like her more than anyone, maybe her and Warren could work as a balance of centrist/progressive, there needs to be something like that to win in a general. Too many Democratic voters are too delusional to not reach out to the different voter blocs. I always say if Hillary had selected Bernie as VP, she could have won.
