What would happen if Democrats changed how a nominee is selected?

13. I think some are and some aren't, depending on how the results are reported.

For example, from the Green Papers tabulation that I was using: It appears that the Idaho Democratic Party reported the number of votes cast for each candidate at the county caucuses, as well as the resulting number of delegates, so the page for Idaho includes raw vote numbers, based on the party's official statement of results. Those raw vote numbers are included in the national totals.

On the other hand, municipal caucuses in Maine choose delegates to the state convention, which then chooses delegates to the national convention. The state party reports only the number of state convention delegates won by each candidate, not the number of votes cast for each. As a result, the Green Papers page for Maine gives delegate numbers, but there are no raw vote numbers to include in the national tabulation.

Also, caucus participation is generally lower than participation in a primary. So, while I agree with you that not all caucuses are included, and that has some effect on the national totals, my guess is that that factor isn't enough to explain the difference of about six million votes between the total in the OP and what the Green Papers gives.
