With four weeks left, supporters of a constitutional ban on same-sex marriage are relying on churches and mailed-in petitions to gather the 100,840 valid signatures they need to make the November ballot.
The mostly behind-doors campaign is taking place after Sunday church services and in the homes, workplaces and neighborhoods of supporters. It's a departure from the traditional approach of collecting signatures in heavily trafficked public places.
And that makes it harder for opponents to be there to persuade people not to sign. That's significant, because it's easier and cheaper for opponents to attack a measure before it gets on the ballot than it is to defeat it at the polls.
