Do you believe there is a scenario where the GOP is still largely in love with Trump and a Trump does not run? That is the only scenario a non-Trump who is/was closely associated with Trump can win the GOP nomination.
Once the GOP falls out of love with Trump, everyone who was closely associated with Trump would be tainted by Trump and would not win the nomination because of the Trump stain anyway.
Pence, Hawley, Cruz, Carson, Graham, Rubio, Pompeo, Paul, Greene, etc., ... none of them have a path around those two scenarios.
