This very detailed and lengthy Washington Post article illustrates which presidential candidates are on ballots in each state, and which states will count write-ins for candidates who aren’t on the ballot. This amount of information about alternate presidential candidates, and even write-in status for them, is completely unprecedented.
The Washington Post has this article about write-ins in presidential elections, with an emphasis on how popular it seems to be this year.
If Gary Johnson or Jill Stein poll approximately 5% of the national vote, the precise national percentage may need to be determined. The question of whether write-in votes cast for presidential candidates who have no slates of presidential elector candidates standing behind them may need to be adjudicated. The denominator (the number of valid votes cast for president in the entire U.S.) might vary according to how that question is answered. Another question might be whether votes cast for “None of these candidates” in Nevada are valid votes. A good case can be made that they are not valid votes, because there are no presidential elector candidates represented by such a vote.
The Iowa Secretary of State’s web page has the election results for President, U.S. Senate, and U.S. House. Approximately 55,000 students participated. The student ballots included all the candidates who are on the actual ballots, so these results provide the first data I have seen for some of the less well-known presidential canididates.
Here is the Minnesota Secretary of State’s list of declared write-in candidates for president. Thanks to Alan Dale for the link.
Here is the official list of declared write-in candidates for all federal and state office in Missouri. The Secretary of State refuses to post this information on his web page, so this is from the Boone County elections office. Thanks to Tony Roza for the link.
