The sacking of Priebus affects us because it is a guide to the turmoil in Trump's personal office and which group is gaining aswcendancy.
When Trump took over as POTUS, he appointed people to his office who, despite some of them being pretty flaky, were Washington people, who could move between the two worlds, Trump world and the broader Washington political world. Over the last few months we have seen some of these being forced to resign by Congress, others being pushed out by Trump.
Trump's recent appointment of Anthony Scarammucci in charge of public affairs aka PR is a move to his core supporters, who have always been anti-Washington and anti-government. The importance of Priebus is that he was, until his recent sacking, one of the saner, more rational middle ground people in Trump's office. His departure, sacked by Scarammuchi, who has accused him, on what evidence I do not know of leaking to the press, No evidence has been published, that I know of indicates that Trump with each problem is walling himself in behind a barrier of very anti-government friends and relations, cutting himself off, more and more from the real world.
This could lead to him and his government taking less and less notice of the elected representatives of the US in Senate and Congress and pushing his personal powers to the limit and over to get his way.
That deals with the sackings
Obamacare. Trump made changing Obamacare one of the central pillars of his campaign. It won him votes. He said he would start to demolish it on Day 1. Six month in he is making his second attempt to change it - and has lost again. Although some republicans d not back his bill because they want Obamacare completely abolished, not just changed. Some republicans have been voting with democrats to keep it.
This shows how both the republican party, never much enamoured of Trump are now actively opposing him. On a personal level as Trump finds it more and more difficult to implement his main campaign promises, it is going to either undermine his voter support, or possibly harden it and it could cause major internal dissension and disorder in the US. It could again, make his government more unstable and his behaviour more volatile.
It is not the individual issues, the sacking of someone in the White House or the reorganisation of Healthcare in US that matters. It is what they are telling us about the current governance of the US and the unstable and volatile nature of its president and his supporters and that is very important to us and we need to realise this.
My apologies for two such long posts. They represent the seriousness of the situation and how little this is understood by many in the UK
