The only thing anyone cares about for the next month is the midterms. A lot of strategy determinations are going to be made solely by POTUS - without Q having authority or anyone else - and be influenced heavily by a desire to win.
Think about it. Trump wants to win 2020 and wants to be as successful as possible. Having majorities in Congress would considerably increase his effectiveness. A unified GOP - old and new factions, around uniquely American principles.
It does make LOGICAL sense.
