Lisa Andrews and Scott Jones immediately struck up a friendship in a political science class three years ago. And today, they aren't just learning about politics -- they work in the field. Andrews is a volunteer for Elizabeth Dole's campaign for Senate, and Jones is a volunteer for Dole's opponent, Erskine Bowles. But as tensions between the two political camps have flared in recent weeks, Jones said he and Andrews have tried to keep their friendship partisan-free. "We used to talk about politics a lot," he said.
