Barbara Bush calls herself "a New Yorker for marriage equality" and says people should be able to marry the person they love.
The former president opposed gay marriage and endorsed a proposed constitutional amendment to outlaw it.
Gay rights advocates believe New York lawmakers may vote to legalize gay marriage this year. Gov. Andrew Cuomo has declared his support for gay marriage, and advocates believe they have enough votes in the legislature to pass it this year.
Barbara Bush lives in Manhattan and runs a nonprofit organization that promotes global health issues.
