Which third party candidates do you believe should be included in the debates?

[Clyde1998]

I'm quite interested to see what the opinion on here is about whether any third party candidates should be included in the debates, regardless of the Commission on Presidential Debates decision to only allow candidates polling above 15% to take part.

Gary Johnson has ballot access to all 538 electoral votes, Jill Stein has acess to 480 (522 with write-in) electoral votes and Darrell Castle has ballot access to 207 (334 with write-ins) electoral votes. As you need 270 to win, all of these candidates could, theoretically, obtain enough electoral votes to win the Presidency.
