The Federal Election Commission has tallied the vote for president by state, for every candidate who was on the ballot in at least one state. Later this on-line chart will be published in a book, Federal Elections 2020. That book, which is free on request from the FEC, will also have the vote for congress. See it here.
These returns still aren’t absolutely final. Pennsylvania still doesn’t have final results because it is still waiting for the U.S. Supreme Court to rule on whether certain late-arriving postal ballots should be counted. Kansas and Maine still haven’t released the write-in totals for declared write-in presidential candidates. Also, of course, there are other presidential candidates who were not on the ballot in any state, but who still got valid write-in votes because they filed as declared write-in candidates in certain states, and therefore did get some votes tallied. It was simply too much for the FEC to include those candidates.
But the FEC chart is certainly useful at this time. For example, the Libertarian Party only retained its ballot-qualified status in North Carolina because its presidential nominee, Jo Jorgensen, was on the ballot in at least 35 states. In reality, she was on the ballot in all states, but it is not so simple to “prove” this. But the FEC chart, because it is published by a government agency, showing that she was on in all ballots, is proof. Thanks to Thomas Jones for the link.
