What are the Consensus in the political stream
Political events move along at their own pace, and according to their own dynamics and rules. Developments in the political sphere can be powerful agenda setters-for instance, a change in government, a change of government ministers, a significant swing in mood of people as expressed in the form of public protests, etc, can all move a subject onto or off of a government agenda.
Consensus in the political stream is generally built more by bargaining than by persuasion. Politicians typically employ a calculus of "political feasibility" to determine whether a problem should be granted a high place on the policy agenda. Often their agenda-setting decisions result more from an analysis of the political costs and benefits of attending to an agenda or a policy proposal, than from the analytic or technical importance of an issue or a proposal alone. In addition, the institutional and political venues in which policy problems and solutions come to be defined and debated are crucial to agenda setting.
