Presidential candidates to face politics of marriage

A review of various legislative efforts and ballot measures in multiple states this year shows that the 2012 presidential candidates likely will be forced to address marriage rights for same-sex couples, especially in states such as Washington, New Hampshire, North Carolina and Maine. 

"There's a lot going on. ... It means that candidates -- whether Romney or Obama -- who hope to avoid the discussion will not be able to," said Evan Wolfson, president of Freedom to Marry.
