I think your scenario is right on Zeev (perfectly addresing the historical sweetspot of election, interest rates) calender-wise. As far as 2500 vs. 2300, I think it all depends of how the sentiment indicators as we go along. Certainly, long-term, can't see how its so so bullish to have higher exhuberence levels (as we are seeing in VIX, etc.) at lower price levels (vs. 1999/2000 etc). But you recognize that too.
However, I am thinking your retrench to 2000-2008 idea (from 2076-2088) may take place starting tomorrow (if we can get to that 2040-2060 area you earlier identified on exhuberent morning up). Wednesday before option ex often a good time to 'take a left turn for a few days'. Since it would take place 20-30 pts. lower, I'm thinking we could go to 1980 on retrench (adjusting your model). Guess we'll know soon enough.
Great job sticking to your guns a few weeks ago at the lows Zeev. I saw Robin Hood taking on all the enemies in the forest there g (not too many arrows left in the rucksack back there, eh?)
