I believe you can sense a seismic shift in the long-term preference of Jews for the democratic party.
The social issues they heavily prefer (abortion for example) still prevent them from a full swing to the GOP, but when a influential and generous part of the Democratic base moves away or to neutral, then the Dems have to be scared and be prepared to throw Obama overboard.
Dems cannot afford to have heavy political donors, influential citizens in many areas of our culture, and sure-to-vote folks decide to change or turn neutral.
Most especially in Florida, and perhaps in other battleground states like Ohio, Pennsylvania, and Nevada.
