As stand alone bills, there are any number of things President Bush will probably veto. The parliamentarians here probably know a whole lot more than I do about the process, but it seems to me that when the Democrats want to pass something the President doesn't like, they will include it in a "must spend" bill - like money to fund the war in Iraq.
Well, since it seems they are more interested in De-funding, or unFunding, or not funding new troops, we may not have to worry about that angle. But I see your point.
