Yesterday, the DKos President forecast was at an 82% likelihood of a Hillary victory. Today, it’s down to 74%. Yet I can find no new polls that would explain this sudden drop. What’s more, the 538 forecast is at 79.1%, which isn't a major movement since yesterday. The NYT one is at 88%, which also isn’t a major movement from recent days.
Does anybody have an explanation of why the DKos forecast is so different from the others?
