90-97. I could see Sanders snagging a few. It's a caucus after all.
I can't wait for the Clinton campaign to resort to attacking caucuses again.
Caucuses are sort of like poll taxes, literacy requirements, and voter ID laws. Their main function is to drastically decrease the electorate by erecting a high barrier (e.g., being able to stand around for several more hours than usual) to voting. They're also unusually susceptible to fraud, manipulation, and arbitrary cutoffs. Regardless the of whether Clinton or whomever your candidate is, is winning them, it's hard to see why anyone who supports democracy could like them.
Except that turnout doesn't matter so much for partisan primaries (certainly not counting California's primaries there), and lower turnout means higher information voters.
