1thru4 are facets of the same thing.
I agree, but I see each as a separate important happening. Scotus, for example, owes its lack of a Scalia replacement to Mitch McConnell.
I might combine them like this: A coalition of patriotic traditional Americans rallied behind businessman Donald Trump who was elected President against all odds. In doing so, Trump essentially took over the Republican Party, redirecting it to support his MAGA agenda, and creating a new leadership team that includes former rivals, the new media, and distinguished leaders of accomplishment from outside government. As a result the GOP retains control of Congress and more state governments than ever, and the ability to recreate a conservative majority on the Supreme Court.
