How many Presidents do you know that have used the line-item veto on every single bill that passes his desk? Because that's essentially what it would take. I'd guess 95% of the bills that are passed into law have some form of "strings" attached. Go look up the process of what it takes from the initial concept of a bill, all the way up to when it reaches the Presidents desk. You have a sub-committee, that reports to a sub-committee, that reports to one of the more "lucative" commitees that debate and dictate if the bill even makes it to an initial vote by the Committee That Votes On It Before It Reaches The House Floor. All during this process, you have the lobbyist, the PAC's, the constituents, and who knows who else poking their input in that it "would be in the best interest of a particular Congressman to add this funding for this "little" project in his home state to the bill. You know, the one's who got you ELECTED." The "You scratch my back, I'll scratch yours" ideology. So they design the bill to where it ends up being 300 pages of legal jargon, with hidden little agenda's mixed in. Of course your elected officials don't have the time to sit down and actually read the thing. That's the responsibility of the 8 or 10 people he has working for him/her on the taxpayer's dime. They just give the Actual Voter the "abridged version". Then there's the back door deals between the Congressmen and Senators - "I'll give you $50 million for that fishery in your home state of Alaska, you give me $35 million for that new NASCAR track in my home state of Tennessee, and I'll back you on your bill." If it ever does reach the President, it's sitting there with 30 or 40 other bills just as long. We know the President has ALL DAY to sit down and read every one from start to finish. I mean, what else does he have to do? There's always that all important 10 o'clock tee time he can't miss....
So you are excusing the practice based off this explanation?
