There has been much chatter about Trump's first one hundred days. Much of the commentary is woefully ill-informed. The discussions are more about whether or not one approves of Trump's presidency than whether or not he is keeping his campaign promises.
There really is no need for this evaluation to occur in a vacuum. Back in October, Trump himself provided the criteria that should be used. I am referring to his Gettysberg Speech. If you have forgotten it, as so many of the political journalists appear to have done, you can refresh your memory here.
It is worth re-reading the speech. If one goes through it line by line, one will see that he has been remarkably consistent (contrary to his representation in the media). Where Trump's promises lie within the executive authority of the president, he has made sustantial progress, even though the courts have attempted to undermine his authority. It is where he promised to work with Congress to introduce legislative change, such as repeal and replace Obama Care, that progress has been limited. The failure to make progress here says much more about the Republican Party than Donald Trump.
Where Trump's first one hundred days can be legitimately criticised in terms of his campaign promises is foreign policy, specifically his repeated claims regarding non-intervention, seeking co-operative relations with Russia and prioritising the destruction of the jihadists. On foreign policy, Trump has abandoned his positions and adopted the policies of Hillary Clinton, the neoliberal globalist elite's candidate. This is a serious failure and betrayal of the people who voted for him.
