Democrats hear from states arguing they should be first to vet presidential candidates

As national Democrats in Washington, D.C. heard from state after state on why they should be among the first to vet the party's presidential nominee, one essential question was repeated: Exactly how diverse is your state? 

Members of the Democratic National Committee's Rules and Bylaws (RBC) committee were evaluating the states, and it's this panel that will end up deciding in early August whether to make a couple of changes to the order states vote in the nomination process or add a fifth state."

The last time the lineup was shuffled was in 2006. Fourteen states applied to be in the early window, and two early states (Nevada and South Carolina) were added. Since then, Iowa, New Hampshire, Nevada and South Carolina have been the first four states to hold Democratic primaries.
