I think 50k a day cut is ambitious, but an 18-20k daily cut is reasonable. If that happens, they will be nowhere near the 653k you project. However, what are the other scenarios where the 2 day trend would be reversed?
With more R counties opening up for early voting this weekend, we should expect R IPEV numbers to improve.
To be clear, my 50K a day reference is not cutting from the overall Dem lead, but rather a daily GOP advantage in IPEV. Dems are expected to continue with daily VBM advantages.
