The argument for debate inclusion is simple, logical, and accessible to even the most partisan among you; the 15% poll threshold is purely arbitrary, we need broader political engagement, not narrower, and if a third party or independent candidate is able to land on enough state ballots to theoretically have a chance of winning, what’s the issue?

Jill Stein Should Be Part of a 4-Way Presidential Debate, by John Nichols (The Nation)

A debate between Clinton, Trump, Johnson, and Stein would represent an even greater improvement.
