There are 932 towns in New York each with a town clerk, according to the New York State Town Clerks Association.
Two clerks have resigned rather than sign marriage licenses for gay and lesbian couples. A third who officiates at weddings in addition to her clerk duties has said she will no longer officiate, but will sign the forms.
So, two divided by 932 gives .002 percent. That’s not a trend, it’s a hiccup.
