The Republican Party and conservatism have had a long history, best represented by Barry Goldwater and Ronald Reagan as its major luminaries, with both assuredly condemning Donald Trump, were they alive today!
Now, vast numbers of conservatives are repudiating the candidacy of Donald Trump, as they well realize he is a total electoral disaster, and his lunatic behavior is causing many of them to back the candidacy of Kamala Harris, as the only way to survive Trump.
So conservatism is still going to be a challenge to Democrats and progressive and liberal values in the future, but the sense is that MAGA Trumpism is a disease, a cancer, that must be excised before conservatism is able to offer a legitimate alternative in the future in the Republican Party.
In other words, purging is essential, and the total defeat of Donald Trump and his followers, who are a threat to American democracy, the Constitution, and rule of law.
