This Florida TV station news story shows which states Gary Johnson and Jill Stein are already on the ballot. Go to the end of the story and click on either the Johnson button or the Stein button. That produces a map showing the states in which ballot access is already assured.
Actually, the Green map is from the Green Party’s own site:

The map for Stein herself is slightly different:

Is the same thing true for the Libertarian Party and the Johnson campaign?
