Would a New Democratic Majority Go Left... or Right?

A county sheriff in Indiana, a retired Army colonel in Kentucky, a former pro quarterback and evangelical Christian in North Carolina: they're pro-business and opposed to abortion, gay marriage and gun control--and they're all running as Democrats in next week's elections for Congress. Potential Speaker Nancy Pelosi promises President Bush would be safe from impeachment, but could conservative newcomers put liberal veterans in check if the Democrats took back the House? Where would that leave the base of the party that's been out of power on Capitol Hill for the past 12 years?
