The Associated Press says gay marriage advocates are "on the verge" even though it's clear they have a long way to go -- we've seen "on the verge" end in defeat for SSM time and time:

The Legislature is on the verge of having enough support to make Washington the seventh state to approve gay marriage, according to a tally by The Associated Press.

A same-sex marriage bill is expected to be introduced by the end of the week. The AP reached out to all 49 state senators over the past week and found that more lawmakers are firmly supporting gay marriage than opposing it, by a margin of 22-18.

The measure needs 25 votes to pass the Senate.
