Hillary Clinton

You used "they should use primaries instead of caucuses" instead of "So for states that already have primaries during the presidential primary season they should use primaries instead of caucuses." Each means something different.

True that the Democratic Party on its own can't make it happen but they can work towards it by having Democratic legislators push for it. And getting a campaign going involving the voters making a demand to have a primary instead of a caucus. Just like it happened in Minnesota. And the reason why it happened in Minnesota? Because the people did not like the way caucuses are conducted. If the people speak loud enough it could be done.

As for punishing good Democrats living in red states aren't they being punished by having caucuses? Not everyone that could is able to vote with the limited hours and accessibility compared to a regular primary election.

The allocation of delegates is based on incentives which is also saying that those not using specific rules don't receive an additional benefit. That won't change. Red states are going to receive fewer delegates than blue states with comparable population. It is a matter of how many.

It is an incentive for red states to support Democratic candidates by increasing voter turnout for our nominee. Doing so increases the number of delegates they will receive for future primaries. My state went from 72 base votes in 2008 to 96 in 2012. It went down to 83 for this year? Why? Because in 2008 they had a campaign in my state and won it the first time since 1964. It went down in 2016 because they didn't target my state in 2012. If Hillary wins this year in my state it will go back up.

For a comparison, Indiana has a population of 6,537,334 while Arizona has 6,553,255. Indiana has 83 delegates to Arizona's 75 delegates.
