Warren continues on a sharp slide in her RCP average for the nomination.
Since her high-point in early October, she has fallen almost 13 points.
That's quite large.
What has happened to cause such a large decline in support for Warren?
And will it stabilize, or will the down-trend continue?
She has lost progressives to Sanders & moderates to Pete. Probably more to Pete. Going by this graph, I would say 7% to Pete, 4% odd to Sanders & maybe 2% to Biden & others combined.
There is a somewhat moderate white rich boomer & above 45 bloc which is shifting from Beto to Harris to Warren to Pete in search of a fresh face. It is such a fickle demographic. This 7% odd bloc got Pete to 11-12% from 5%, it has got Beto to 11-12%, it got Kamala to 15% (That & some Black Biden voters), it got Warren to 15% (That & some Sanders voters who has since gone home). I am not sure that bloc is even a reliable voting bloc for any candidate.
If Warren doesn't have a strong debate & loses her momentum, she will bleed more Bernie 2016 voters since Sanders is now the 2nd choice. She needs an incredibly strong debate & she needs to take voters away from Pete.
