The May 20 primary will determine who will vie for the U.S. Senate, governor of Oregon, and whether Portland's water remains in the hands of City Hall. The election could also determine who will take over as chair of Multnomah County, Jim Francesconi and Deborah Kafoury.

If you want a voice in those decisions, and you're not registered to vote, you have until 5 p.m. today to register at the Multnomah County Elections Office at 1040 SE Morrison St. Or you can do so online until midnight.

Check back tomorrow for WW's voters guide, when we make public our endorsements.
