In the following paragraph, does "successive administrations" refer to Bush's 2 terms in office?
Feeding the Oil AddictionMoreover, as the bill wound its way through Congress, the White House rejected a number of measures that might have eased America's addiction. It quashed, for example, the creation of a national "renewable portfolio standard" that would have required utilities to get a certain percentage of their energy from renewable sources, something several states have adopted. It rejected an "oil savings amendment," which would have required successive administrations to find ways to reduce oil use. It spurned any suggestion of automobile fuel efficiency requirements.
I would understand it to mean "future administrations." Presidents who follow this term.
