Just Remember Richard Nixon
What checks will there be on a Donald Trump presidency? , The potential checks are many, including Congress and the Courts, the free press and many internal Executive branch watchdogs like inspectors generals, lawyers and the permanent bureaucracy. And of course the people in the next election. Will they work?, It depends on what Trump tries to do. If he tries to follow through on pledges that are clearly unlawfullike re-starting waterboarding, or worseI am sure the internal and external checks will prevent that. But there are many lawful decisions the president can make and implement that will not be checked. One obvious example concerns the domestic clean air regulations and the related international agreement President Obama famously forged. Trump can and likely will kill those. Constitutional checks do not prevent presidents who win elections from changing executive branch policies. What will it mean for all three branches to be controlled by one party? , It will mean that Trump has an enormous opportunity to implement his agenda, especially in the short term. , Is there historic context to Trump's approach to executive power? , Hard to say since we don't really know what his "approach" is. To the extent he is promising to disregard or abuse the law, the obvious analogy is Richard Nixon. And the reaction to Nixon is an obvious guide.
