Art of Strategy describes a debate from 1990s US politics revolving around so-called “line-item veto” power, the ability to veto only one part of a bill....During the '90s, President Clinton fought pretty hard for this power, which seems reasonable as it expands his options when dealing with the hostile Republican Congress.

Just for the benefit of those who don't know the history (and won't bother to click on the Wikipedia link), it should be noted that the Republican Congress happily gave Clinton this power (perhaps not so surprising after reading this post!), but it was struck down by the Supreme Court (which functions as America's House of Lords -- kind of a mirror image of how the actual House of Lords used to function as Britain's Supreme Court).
