Republican Pennsylvania Gov. Tom Corbett, perhaps the nation's most vulnerable governor up for re-election next year, compared gay marriage to incest between a brother and sister, the Philadelphia Inquirer reports.
Corbett won election in 2010 by an even larger margin, 54 percent to 46 percent. But according to a June Quinnipiac poll, the governor's approval rating stood at just 35 percent.
