Vice President Joe Biden has been talking to friends, family and donors about jumping into the presidential campaign. Follow the hyperlinks below for thoughts about his prospects:
• Biden's dying son urged him to run. But that's not why he'd do it, writes Joan Vennochi of the Boston Globe. He'd run because he wants to, and because he's as well-placed as anyone to win.
• But whatever the chatter among pundits and political professionals, Jonathan Bernstein of Bloomberg View argues, the vice president doesn't appear to have any natural constituency or any real opening.
