Thanks. I think what the pragmatists are missing is that a big part of the reason we got Trump is that many voters were dissatisfied with the status quo, as represented by the centrist Democrat approach of the Clinton-Obama period. So going back to that previous status quo does not seem like a long-term solution, even if Biden was able to defeat Trump because voters are turned off by Trump's behaviour.
I also think it's a mistake to think of this about being about one bad guy who hijacked the Republican party, so if we get rid of him things will go back to normal. Trump was pushing on an open door in 2016 - he just capitalised on trends that were already well under way in the party and took them further. There will be others who saw what worked for Trump and appeal to the same themes. That's why I object to buttslinger's view, which seems to assume that Trump is an aberration and normal service can be resumed once Republicans wake up.
That's not to say there there would be no benefit in getting rid of Trump, because his malignant narcissism and erratic nature pose additional dangers.
