scale

[Edit: the low numbers seem to be be bunk; I was trusting the report of Google [washington caucus] and such, but e.g. http://www.huffingtonpost.com/michael-p-mcdonald/iowa-caucus-turnout-what-it-means_b_9141408.html and http://iowademocrats.org/statement-from-idp-chair-on-tonights-historically-close-caucus-results/ report much higher Iowa numbers. http://www.dailyjournal.net/view/story/05a3e761e16d4aa2beaa47c294f76071/WA--Washington-Caucuses-Democrats talks about 250,000 turnout, and 26,000 "delegates".]

Alaska caucus: 539 votes. That's not a margin, that's how many people were at the Democratic caucus. (The GOP had about 20,000 people, still small but a lot bigger.)

WA caucus was 26,000 people for the Democrats. The MA primary had nearly 1.2 million voters on the Democratic side, and MA has somewhat fewer people than WA.

HI is similar to the other caucus numbers (AK Democrats seems exceptional.)

Iowa caucus was over 150K for the GOP. About 1400 people for the Democrats.
