Balderdash. You're not paying attention.
Here are seven big issues currently being debated where there is or was significant daylight between the two parties:
1. Whether to spend the budget surplus or not; the latter would make possible a significant expansion of domestic discretionary spending for useful purposes;
2. Social Security privatization.
3. New right-wing proposals for a 'trillion dollar tax cut.'
4. Patients bill of rights, prelude to potential comprehensive regulation of HMO's and reopening of health care debate;
5. Free trade (currently, a NAFTA-Africa bill is in play)
6. Tax reform: flat tax versus increasing the progressivity of the current system.
7. The highway bill, a significant expansion of public works which defied the conventional wisdom about deficits and government spending.
I do not include the tobacco settlement or campaign finance reform because these are less clear-cut in their purposes, effects, and degree of associated party partisanship.
I should qualify that "two parties" on some of these issues (particularly 1 and 5), means the Republicans, the Clinton Administration, and the Senate on one side, and the House Democrats on the other.
