Suburban voters will be key in the 2000 presidential election, and candidates are courting the suburbs with different approaches.

But rather than framing the issues as environmental, he’s connecting them to families, speaking of parents “on the car phone talking to their kids, explaining why they can’t get home for dinner.”
