I would argue that what is happening to the GOP is a continuous progression that began with Nixon's Southern strategy. It is not a cycle, but an incremental iteration in nationalist, racist garbage.
Nixon, Reagan, GW Bush, Trump. Each one worse than the predecessor, with Bush 41 being the only outlier.
And, as an aside, there is no logical reason to believe that Covid19 will be a memory by November. This thing is with us until we have a vaccine, and we have not seen the worst of it yet. It's just begun in rural areas where there isn't much medical infrastructure. Georgia is a good early example.
And yeah, it's going to shape an entire generation, same as the depression did, same as world war 2 did, same as 911 did.
What can we do to help you stop screaming?
