Jim Webb is probably to the right of Hillary but he's not likely to get much support--maybe from some old "yellow dog" Southern Democrats who haven't been paying attention to what has happened to their party over the last 30 or 40 years.
If Bernie looks like he is a real contender, Liz Warren may decide she should run after all. Like Bobby Kennedy jumping into the race in 1968 after Eugene McCarthy almost beat LBJ in New Hampshire.
