You might hate her politics and hope that her son doesn't become the next President, but Roberta McCain is kind of a cool old broad. At a rally in Boston today, her son John told the audience about how his mom recently decided she wanted to see France for the first time, so she hopped a plane there and went to rent a car. The French told her she was far too old to be allowed to rent a car (she's 95 now) and tool around France. So she bought one.
