You just don’t understand. For a very large number of Republicans character doesn’t matter any more than core conservative principles matter. All that matters to that group is someone be a Republican who they think can win.
And what matters to many is proven accomplishments and not mere rhetoric.
Some want to hear the right words on Abortion (and other "social" issues) and they have their candidate even though every Republican candidate since Roe has been anti Abortion and changed zip.
Nothing but nothing, when electing a President, transcends foreign and security affairs in these perilous times.
The character of all the candidates is subjective. Accomplishment in few rare cases is obvious and striking.
