Cuba's communist government is attempting to garner support for a new family law that would allow same-sex marriage and strengthen women's rights.

But according to NBC News, experts and a recent poll suggest that an impending referendum vote will not be a rubber stamp.

In the midst of a government campaign to foster free and candid discourse, lukewarm support for the measures, which contrast with the island's established "machista" culture, threatens to deliver state-backed supporters a loss.

The proposed 100-page code, which is being debated in town-hall-style sessions around Cuba, brings together a slew of new family-related rules. It repeals various laws enacted in 1975 under the presidency of former Cuban President Fidel Castro.

The new code would make same-sex marriage and civil unions legal, enable such couples to adopt children, strengthen women's rights, and encourage equitable household responsibility sharing. Prenuptial agreements and assisted pregnancies are among the innovations included.
