Definitely, Julia -- I'm all for unpacking the whole "Joe Biden effect" this year. There doesn't seem to be a single policy that unites the Joe Biden supporters -- or the supporters of Rep. Cheri Bustos or even Rep. Tim Ryan. But I do see a coalition of politicians who do seem to be emulating Biden. Maybe it's a personality thing? Or just a refusal to be tied to any one policy? But I don't think those politicians fall neatly into a Bernie or Hillary wing, either.
