I’ve been asking the same question since the debate. The morning after, it was 50/50. By that afternoon, it was 60/40 in favor of Biden being replaced. This morning, it was 45/55 in favor of Biden remaining. I find the addition of “by certain dates” interesting.
A lot of what-if analysis is possible, and can really suck up time. A few days ago I started asking questions, re-phrasing them, and next thing I realized I had spent nearly three hours.
