As I only pop in here from time to time (it is much more fun upsetting the fundamentalist Christians at meetchristians.com) I apologise if I am starting a topic which has already been discussed.
Because I know almost nothing about the American political system, I would like any opinions as to how much the Democrat controlled parliament can influence the decisions and policies of the Republican administration.
Naturally plans for withdrawal from Iraq are the hottests issue, but no doubt there are many domestic issues on which the Democrat parliament will oppose the Bush Administration.
How much influence do they have?
