The April 22 Pennsylvania primary is April’s only Democratic Party nominating event. After that, the next round is the Guam caucus, which has received little publicity. Guam Democrats will choose 4 delegates on Saturday, May 3 (actually, though, 8 will be chosen, and each will have a half-vote). Caucuses will be held in all 19 municipalities. Any registered Democrat may participate. Voters vote directly for candidates for Delegate, using paper ballots supplied by the party. Filing to run for Delegate closed on April 18.
Republicans held their Guam caucus on March 8. John McCain won that event.
Guam is the only U.S. possession that also votes for president in November. However, since Guam has no electoral votes, the November presidential vote doesn’t actually affect the national outcome. The Guam vote for president in November doesn’t even rate a mention in U.S. newspapers. In 2004, the November vote was: Bush 21,490; Kerry 11,781; Nader 196; Badnarik 67.
