Jill Stein, Green Party nominee for president in 2016.
A Morning Consult poll earlier this month showed that 52 percent of voters wanted Johnson on the stage at the first debate, and 47 percent said the same about Stein.
The nominees of the Libertarian and Green parties will not appear in the first presidential and vice-presidential debates after decisively missing the 15 percent polling threshold established by the Commission on Presidential Debates. According to an average collected by RealClearPolitics, Johnson averaged 8.4 percent support in the basket of polls, while Stein averaged 3.2 percent.
In announcing that it invited only Hillary Clinton and Donald Trump to the September 26 event, the non-partisan, non-profit Commission on Presidential Debates said it "applied its Nonpartisan Candidate Selection Criteria" - polling requirements that left out Johnson.
The CPD noted that the criteria for qualifying for the debates will be reapplied to all candidates in advance of the second and third presidential debates.
Johnson, a former governor of New Mexico, has said that participation in the presidential debates was crucial to his candidacy. "It should be noted that, when [Ross] Perot was allowed on the stage, polls showed his support to be in single digits, below where Johnson and Weld are now polling" he said.
Republican nominee Donald Trump and Democratic nominee Hillary Clinton
In addition, only the major party candidates, Republican Mike Pence and Democrat Tim Kaine, have qualified for the vice-presidential debate to take place on October 4 at Longwood University in Farmville, Virginia.
Johnson said he wasn't surprised by the decision to "exclude" him from the first debate.
Clinton and Trump have both previously confirmed that they will participate in the first debate, set to take place September 26 at Hofstra University in Hempstead, New York.
"The CPD may scoff at a ticket that enjoys "only" nine or 10 percent in their hand-selected polls, but even nine percent represents 13 million voters, more than the total population of OH and most other states", Johnson said in a statement.
The debate will feature only Democrat Hillary Clinton and Republican Donald Trump.
"It is unfortunate that the CPD doesn't believe such a voice should be heard", Johnson said.
