anecdotal: Went to a party for an old friend last night

saw many people I hadn't seen in years.
Most know me for my democratic politics.
Many came up to me to tell me that they would be at the caucus for Bernie on Monday.
All volunteered, I didn't ask anyone.
No one volunteered that they were going to support Hillary.

That doesn't mean anything when it comes to what will actually happen Monday, but even I was surprised.
