Washington Post: The million-dollar question on the election’s eve: Who is left to vote?

More than 98 million Americans had cast ballots by Monday evening, an astonishing figure equal to about 70 percent of the total turnout four years ago — leaving election officials, the campaigns and the public overall wondering how heavy voting traffic would be on Tuesday.

While at least three states — Texas, Hawaii and Montana — exceeded their total 2016 turnout with early and mail voting this year, other states have seen lower turnout that could foretell heavier Election Day traffic. Among battlegrounds, Pennsylvania had reached only about 40 percent of its 2016 levels by Monday, Ohio had hit 60 percent, and Michigan was also at 60 percent. …

“We are confident we’ll see record turnout here by the end of the election night,” said Quentin Turner, who runs the voter protection operation in Michigan for Common Cause, a nonpartisan group. “We are a little above 50 percent of our 2016 total in early votes alone. Many folks in Michigan want to vote in person; it’s an important tradition here.”
