Supporters of gay nuptials are planning to capi­tal­ize on the return of the General Assembly with a “Marriage Equality Lobby Day” on Monday and a call-in campaign during the session’s first three days.

E-mails were sent out Friday to members of several groups that are part of a new coalition known as Marylanders for Marriage Equality.

The e-mail contains a link for Marylanders to find out who their delegates are, as well as a suggested script to use when they call their offices in Annapolis.

The script goes like this: “My name is _________. I live at (address, city, state, zip) and I’m a voter in your district who strongly supports civil marriage equality because all loving and committed couples should be able to marry, including gay and lesbian couples.”

Callers are also encouraged to add something personal, such as a reference to a gay family member.

The call-in campaign comes as both sides gear up for a rematch in the regular session next year over one of the most contentious social issues Annapolis has debated in decades.

This year, a bill cleared the Senate but fell short in the House. Gov. Martin O’Malley (D), who has announced he will sponsor this year’s bill this year, appears in the first of a planned series of videos promoting the issue.
