This … doesn't match my experience. I was a NPP voter in CA; as I remember it, last year, I just walked in, the tables/lines were well labelled, and I was either asked which ballot I wanted or I simply pointed to it since they were laid out on the table. I recall no trouble voting in the Democratic primary.

(Now, that was last year. I've since left CA, as it was too expensive.)

(This release[1] does seem to corroborate what the article says, though.)
