Trumps presidency was planned from the start to get him to do the dirty work that couldnt be done in a politically correct environment Think about it every president before trump had been a politician before hand and thus always had to balance getting the agenda out there while still having support of the public which ultimately resulted in half ass response 
Trump was basically selected so america could tie up loose ends without bureaucracy stopping him
He got muslim countries to recognise israel he stopped the iran deal he "built the wall" he took the heat for imprisoning children at the border( started by obama) 
Now that his work is done time for damage control so joe gets the presidency to create a softer image while furthering the same agenda 
This is all my own opinion based on my own analysis not based in any facts
