I've got mixed feelings. On one hand if they can't clear 15% they're just a candidate to throw away votes on. And adding another four candidates to the debates means that only a third as many questions can be asked.

And I feel debates are important to the election process because I think a fair number of Americans aren't doing independent research and may base their choice on them.

On the other hand without inclusion it'd be really hard for a third part to grow to a credible level.

I suppose I would support a mix. Either some debates with all and some without. Or perhaps some debates where it starts off with everyone and then in the second half it's rapid fire questions for the frontrunners.
