Signs of a Biden win: If the polls are right and the count is on track, Mr. Biden is probably getting a Wisconsin and Nevada call on election night. Georgia’s another possibility — if Mr. Biden is going to win the state, he has probably caught up to Mr. Trump by now. If the night’s going really well for Mr. Biden, maybe he’s still competitive or even leading in Iowa, Ohio or Texas.AdvertisementContinue reading the main storyMichigan and Pennsylvania? Well, we’re just going to have to wait and see. Of the two, Michigan seems more plausible.Exactly where will the count stand in Michigan and Pennsylvania if Mr. Biden’s on track for victory? It depends on how many absentee ballots they get through, of course. If they haven’t counted many mail ballots, Mr. Trump could even lead by double digits.The better measure: Focus on any counties that manage to wrap up their count. I’d guess some will get pretty close. If Mr. Biden’s winning, he will start to outrun Mrs. Clinton’s 2016 showing in the counties that get through their mail votes. That could be the tell.Signs of a Trump win: If the president’s on track, the race in Nevada and Wisconsin might be too close to call. Even if he eventually loses Wisconsin, he might hold on to the lead all the way until we get the absentees from Milwaukee. He probably already got the call in that long list of states where Mr. Biden’s hoping to squeak out a win, like Ohio and so on.The most important sign would be a lead in Pennsylvania and Michigan. In Pennsylvania, it could easily be a double-digit lead, depending on just how many absentee ballots have been counted. With Mr. Biden holding such a commanding lead among the third of the electorate that voted early, a Trump win most likely involves a double-digit victory on Election Day — and a double-digit lead in the count, late into the night.
