The gay half-sister of Republican presidential candidate Newt Gingrich slammed his position on gay rights on Wednesday and said she will support President Barack Obama, a Democrat, in the 2012 election. Candace Gingrich-Jones, a gay rights activist, told MSNBC's Rachel Maddow that she and her older half-brother, the former speaker of the House of Representatives, were "mutually respectful" but disagree on gay rights. "He is definitely on the wrong side of history when it comes to those issues," Gingrich-Jones said.
