For the 2016 presidential election, only six states require more than 25,000 valid signatures to get on the ballot, if one looks at the easiest method to get on the ballot for an independent presidential candidate or the nominee of an unqualified party.

Those six states are California, Georgia, Indiana, Michigan, North Carolina, and Texas. Illinois requires exactly 25,000.

No one knows exactly what the Pennsylvania 2016 requirement will be, but in both 2008 and 2012 it was less than 25,000. The 2016 number will be determined by the turnout in the November 2015 statewide judicial election. It is also somewhat likely that the Pennsylvania law will be liberalized by the legislature this year.

By contrast, in 1992 there were ten states in which there was no way onto the ballot without a petition or registration drive of more than 25,000. Those four additional states were Florida, Oklahoma, Oregon, and Pennsylvania.

Alexandria, Virginia elects a Mayor in a partisan election on November 3, 2015. Incumbent Mayor Bill Euille will run for re-election as a write-in candidate, according to this news story. He will make it official on September 7. He must be a write-in candidate because he lost the Democratic primary on June 9, and it is too late to file as an independent candidate.

The Deseret News, one of the daily newspapers in Salt Lake City, has this story about the hopes of some Republican Party activists who hope Mitt Romney will be the 2016 Republican presidential nominee. The story mentions that many states have November 2015 deadlines for candidates to enter Republican presidential primaries. No state has an earlier deadline that November 2015 except for South Carolina, where Republicans file by September 30, 2015.
