A quick, but interesting, data point.
Wife went to the local polling station today to vote in the primaries (and on California referendum initiatives), just before they closed. She was #179 on the day... and #108 to use a paper ballot, instead of the available touch screens.








One of the two polling places I run ran out of DTS-DEM ballots (the ballots for DTS voters who want to vote in the Dem primary) at about 6.45pm. The county did not provide us with more.
Both of the polling places I run, plus the other two in the same building, ran out of provisional ballot envelopes at around 7pm; the county got us more of those at 7.50pm.
