Elaborate on the influence that governors have in changing policy

What will be an ideal response?

An ideal response would be:
Although governors' formal powers vary widely from state to state, to change public policies, all governors face the challenge of securing the cooperation of many other people and institutions. To enact new legislation, governors may need to bargain with top legislative leaders (often of the opposite party), interest group representatives, local governments (which often lobby for or against legislation and budgets), and the state's bureaucracy (whose expertise is sometimes important in getting legislative support). In some cases, governors need to negotiate with federal agencies for a "waiver," an agreement by a federal agency to permit a state to implement a state law that would otherwise conflict with federal law. Governors must use their formal powers, political strengths, and personal skills to persuade these and other largely independent people and institutions to do what the governor needs them to do, usually by making it clear to such people that it is in their own political interest to do so.
