The Politico web page that shows election returns changes every day. Most state election officials make available a running tally of votes counted, and the people in charge of the Politico page note those changes and include the new figures. However, not all state election web pages show any election returns; these states post no figures until they are final. For those states, of course, the Politico figures haven’t been changing and merely reflect the election night tally gathered by news media.
Adding up the totals as of the evening of November 13, Gary Johnson now has 1,206,361 votes. There are no write-in vote tallies for him from Michigan yet, but there will be when Michigan finishes its tally.
