In general, Conservatives think Government is the problem.   Liberals think governmentis the solution.

In specifics:

Liberals want:
Less spending on the military
More spending on low income
Affirmative action programs and quotas
Tax increases to support this spending (especially on the rich)
Gun Control
Less emphasis on religion and certainly not in public places
Abortion at any time
No proactive military interventions overseas
Sign Kyoto protocol
More goverment programs- safety net from cradle to tomb

conservatives want
More spending on the military
Less spending on low income and welfare
No affirmative action and quotas
Tax cuts for all working people
Freedom to own guns
Support of Christmas, manger scenes, the 10 commandments, and pledge of allegiance
Pro life (although I am conservative and pro choice)
Proactive military operations
No Kyoto
Less govenment programs and regulations- freedom to succeed or fail.

Neither side has a coherent view on immigration, but then again neither side has a cohernet candidate.
