The Senate has scheduled a floor vote for Wednesday, and a majority have already announced they’ll vote for the bill. Supporters say House passage is also assured. Gov. Christine Gregoire supports equality.

Washington is a referendum state so once the bill passes and the governor signs, the opposition will have until June to collect 120,557 valid signatures to put the issue on the November ballot.

If marriage equality becomes law, Washington will be the seventh state to perform same-sex marriages. The state already has domestic partnerships.

Two additional states — Maine and California — passed marriage equality before voters rescinded it.
