At this point, Biden is the president-elect, with every major network including Fox having called the election in his favor, and with a probable end result of 306 electoral votes to 232 for Trump. That assumes that Biden retains Arizona and wins Georgia, and Trump wins North Carolina and Alaska. That said, a number of commentators and pundits have noted that his margin of victory, which currently is around 3% in the popular vote, is smaller than the polls would have predicted considering that Biden polled at an average of 8.4% over Trump in the days before the election.
However, while most eyes may have been on vote counts in swing states, many other states are still counting, even though their electoral results have not been in doubt. These states are disproportionately Democratic, and if the ballots still being counted are primarily absentee ballots, one might expect them to favor Biden. For instance, California has only counted 86% of its votes, suggesting that about 2.2 million are left to count. We might expect the uncounted ballots to increase or at least change Biden's percentage of the popular vote. On the other hand, there are a few states like Alaska that lean Republican and have also not counted many votes.
Are there any forecasts of Biden's likely eventual margin of victory in the popular vote?
