the distinction does make a difference for the legislative branch, which does not have a line-item veto.<p>Let&#x27;s assume that X is &#x27;punish pedophiles&#x27; and Y is &#x27;allow corporations to dispose of 10% more toxic waste in upstream waters without liability if they own the surrounding land for up to two miles.&#x27;<p>Then if a legislator votes against the bill they have voted against punishing pedophiles, that&#x27;s not going to look too good around election time. This puts more power in the Executive branch, and means essentially you&#x27;re depending on the Executive&#x27;s good will not to allow corporations to dispose of 10% more toxic waste.
