Spotlight PA has a feature on Pennsylvania school board elections with closed primaries (you’ve got to be a member of the party to vote in that party’s primary) and cross-filing (in which candidates can appear on multiple parties’ ballots).

I’m told that candidates who filed in two primaries and won both would appear on both party lines in the general election, making this a form of fusion voting.  (Related but unrelated, there’s more news in fusion: across the Delaware, there’s  news yesterday that a suit contesting a fusion ban in NJ can proceed.)
