A few Republican Party leaders have expressed the idea that somehow, the party should keep Donald Trump out of its upcoming presidential debates. This National Journal article explains that federal campaign finance laws do not permit that. Debate sponsors must use objective criteria, such as poll results, not political criteria. Thanks to the Center for Competitive Politics for the link.

Lyndon LaRouche never did well in any public opinion poll, so it was easy for him to be excluded from primary season Democratic presidential debates.
