ELI5: How come there has been multiple GOP debates, but only one Democratic debate?
gpt
It is completely up to each party's leadership - the Democratic National Committee (DNC) and Republican National Committee (RNC) respectively. 

The main reason the Democrats have so few debates this election is that the Democratic establishment - including DNC chairperson Debbie Schultz, who decides the number of debates - would like to see Hillary Clinton nominated. Because Clinton has such a huge lead and near universal name recognition already, she has little to gain from debates and everything to lose if she makes some kind of gaffe. Therefore, the DNC limited the number of official debates this election cycle to protect her lead. The DNC also created a rule that no candidates may participate in unofficial debates or else they will be blacklisted from the official ones. This is not to say Hillary Clinton did anything wrong, this is just the politics of what happened.
