When Republican Sen. Rob Portman of Ohio announced his decision to support marriage equality in March of 2013, he explained that his change of heart on the issue came after learning that his college-age son, Will, is gay. “It allowed me to think of this issue from a new perspective, and that's of a Dad who loves his son a lot and wants him to have the same opportunities that his brother and sister would have," Portman told local reporters.
The immediate question at the time was how the Ohio freshman senator’s reversal on gay marriage would affect his re-election chances in 2016. Running in the battleground state of Ohio would guarantee a close race no matter what. Going it alone as the first Republican senator ever to support marriage equality meant Portman could be risking his seat, if not his career.
