Washington United for Marriage responded to the signature submission:
This basically makes it certain that in four states this fall there will be campaigns and public votes on marriage equality, with three of those votes ending up in legalizing civil marriages of same-sex couples if the electorate supports the equality position. The four states are Maine, Washington, Maryland and Minnesota with Minnesota's vote on adding a constitutional amendment to ban marriage equality (similar to California's Proposition 8) in a state which already has a state law banning the practice. Happily, the latest poll shows that Minnesota's ban is likely to fail.
In fact, in all 4 states support for marriage equality is increasing and is almost above 50% outside the margin of error of recent polls. (Maine is at 54%-41% as of March 2012, Maryland is at 57%-37% as of May 2012 and Washington is at 54%-33% as of May 2012.)
