Google is raising awareness of the equal marriage public ballots that are due to take place in Maine, Maryland, Minnesota and Washington next month with a new campaign video featuring its staff.

The video was produced by the same team that created Google’s It Gets Better film.

A UK version was released in partnership with Stonewall last year and featured Prime Minister David Cameron, comedian Rhona Cameron and the DJ Jodie Harsh.

In the new US video, Google employees talk about what marriage equality means to them.

The release of Google’s video came in the same week President Obama gave strong personal backing to the supporters of equal marriage in Washington.

Although Washington’s Governor Chris Gregoire signed into the law an equal marriage bill earlier this year, anti-gay opponents were successful in gaining enough signatures for the decision to be put to a public vote on 6 November.

Maine and Maryland will also vote on marriage equality on the same day.

In Minnesota, voters are being asked to decide on a constitutional amendment that would define marriage as only between one man and one woman.
