Risking 3.6 units to win 2.
The bump mayor Pete got from Iowa looks like it is slowing down since Biden supporters have gone to Klobechar as much as him and the 2 most recent New Hampshire polls show Sanders with a clear lead and Klobechar beating Biden for third.
The polls in Nevada show Biden and Sanders nearly tied, but Sanders should win New Hampshire by a solid margin and it looks like Klobechar will beat Biden for third. With Biden likely finishing 4th or worse in New Hampshire I expect voter and unions to back Sanders. The caucas system favors younger voters and strong organizations, Sanders has the far younger voters and better organization than Biden, and the Sanders campaign has far more money than Biden. Sanders voters remember getting screwed in Nevada in 2016, they will be better organized this time.
