The virtues that Hillary Clinton identified in Tim Kaine are also the ones that have led her astray in the past.
In 2008, Barack Obama famously wanted a “team of rivals” in his administration. He began with his running mate, who was utterly unlike him. Obama was a political newcomer; Joe Biden was a Beltway veteran. Obama appealed to African Americans and upscale liberals; Biden appealed to blue collar whites. Obama was disciplined; Biden was unruly. Obama was cool; Biden was warm.
Hillary Clinton, by contrast, has chosen a male version of herself. Like Clinton, Tim Kaine is a culturally conservative liberal. He’s a devout Catholic who personally opposes abortion despite believing it should be legal. For her part, Clinton is a devout Methodist—she’s taught Sunday school, lectured on Methodist theology and participated in various prayer groups—who is personally skeptical of abortion, too. In 2005, she called it “a sad, even tragic choice to many, many women” and looked forward to the day when “the choice guaranteed under our Constitution either does not ever have to be exercised or only in very rare circumstances.”
