*The gay half-sister of Republican presidential hopeful Newt Gingrich is not only criticizing his position on gay rights, but has already said she is voting for Barack Obama in the 2012 election.

Candace Gingrich-Jones, a gay rights activist, said in an interview with 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.

She said she would “work really, really hard to make sure that President Obama is re-elected next year no matter who the Republican candidate is.”

Gingrich’s campaign nearly sputtered to a halt last summer, but he has recently risen to the top of the polls in the Republican contest to choose a nominee to face Obama in the 2012 election.
