**Quite a few of Cruz’s people supposedly quit yesterday. I wonder if this is why?**
Good guess. I was just thinking the same.

The text from the flyer reads:
You are receiving this election notice because of low expected voter turnout in your area. Your individual voting history as well as your neighbors are public record. Their scores are published below, and many of them will see your score as well. CAUCUS ON MONDAY TO IMPROVE YOUR SCORE and please encourage your neighbors to caucus as well. A follow-up notice may be issued following Monday's caucuses.
----
First there's the accusation of a 'voter violation', then a follow-up notice may be issued following Mondays caucuses, and if you don't vote we will tell your neighbors.
Sounds like intimidation and threats to me.
