Trump has already shown he can make changes to his admin. Sessions was a terrible choice and will be very bad for Trump. A huge part of the working class people that voted for Trump will like to smoke and will turn on him. ESPECIALLY with Sessions having such a hardon for going against state's rights.
What politics from both sides wants to teach us is that things are never complex. If you have your little package and something doesn't fit into that package, You don't know what to make of it so you want to dismiss it or then you will have to do the work of reconsidering your assumptions. - Michael Malice
