Sorry to be so lazy...
But isn’t the simplest assumption set to
1. Note the Dem VBM count advantage.
2. Estimate the Eventual (Voting Day) VBM advantage (raw number) and the total VBM turnout (raw number)
3. Note the current IPEV D/R ratio.
4. Estimate (guess) the total election turnout from total registrations.
5. Subtract the VBM total
6. Extend the the IPEV ratio for the entire IP number.
Tell us all who wins and thus get our gratitude and great glory.
Chime in tomorrow with your prediction.
All welcome.
