IF, Joe really did do poorly last night. And if Pete did very well, that is bad for Joe. One, this will get people in NH to shift over from Joe to Pete, possibly Bernie. And then by the time super tuesday comes along, Pete and Joe will be both have their moderate lane lunch eaten by Bloomberg. And like you said, Amy won't have the resources to make it much farther.
So then you may get yourself to a race with Sanders and Bloomberg at the top and Biden, Pete, and Warren a distant 3,4,5.
The pluses I see for both Sanders and Bloomberg are this.
Sanders is a fighter. He is still sharp enough to debate well, and he plays a lot of the same tricks that Trump does which is a good thing. Also he has a supremely loyal base which helps, and he has been doing much better with minority voters this time around.
Con for Sanders: He can be boiled down to a 2 word label by Trump. Crazy Socialist. Unamerican, blah blah. And that will stick with a lot of people.
Bloomberg. Let's face it. He has the money and resources. He has put out really good ads thus far. He is also putting lots of money into downballot races. He is also someone that I think could dismantle Trump on the debate stage. He's got the sort of tough, get things done persona that appeals to moderate repubs, while not being one of the most disgusting people on earth.
Con: Trump, in most hypocritical terms
will hit him on stop and frisk. Maybe call him something really catchy like "Stop and Frisk Mike" And obviously he does legitimately have issues in the minority community to fix.
