First off, I'm in Greene County and Sanders got 33 delegates to Clinton's 22 which should put to rest fears of the 49.6 / 49.4 split mentioned in the Crisis article, so all is well there. Edit This means the rules DIDN'T change and delegates were allocated proportionally
On another note, tonight I gained some insight that was actually pretty interesting and I want to post this because I heard some articles are out there about Bernie potentially winning MO. Brace for incoming wall of text.
So in each country/district, delegates and alternates are elected to represent at the state convention. So in this example 33 delegates and 33 alternates were selected for Bernie. The alternates show up to the state convention in case the elected delegates can't make it and sub in as votes. So for a county If all 33 elected delegates show the alternates basically hang out on the sidelines.
Here's the cool part: if a small country didn't fill their delegate seats at the county convention, alternates from larger counties can sub in for them. So if I'm an alternative from the larger Greene county, and all my Greene county elected delegates show up, I can go sit in as an elected delegate for a smaller neighboring county who may not have filled every allocated Bernie seat.
Edit: Sanders HASN'T won Missouri yet. But read below.
So here's the potential Bernie flip scenario (which is rare, but possible). If a seat is left vacant, that vote is gone. So if I don't have an alternate to fill that spot I lose a vote. If HRC can't cover all her vacancy spots in smaller counties with alternates from larger counties, Bernie could potentially pick up more votes if he's able to fill all his seats.
Again this is a rare scenario, but when I learned about this it really clarified that whole "Nevada-retroactive-win" situation.
