I saw an article about this question online years ago.
https://slate.com/news-and-politics/2012/06/fixing-the-constitution-electing-the-attorney-general.htmlThis plan has some disadvantages, as it forces Attorney Generals to be able to wage national campaigns. And it creates a launching pad for the White House that is limited to lawyers.
But I can't help but wonder who would have won the elections, and how that would have changed things.
Geraldine Ferraro might have been elected to the office in 1986, as a former prosecutor with national name recognition. Or the same things that doomed her senate campaigns could have doomed this.
If John Kerry had run and won in 1998 (he had the resume and it was a cycle in which Democrats were competitive) he probably would have been Gore's running mate.
2002 would almost certainly have seen the election of Rudy Giuliani to the office.
2006, assuming similar political circumstances, would have been a very Democratic year. I could easily imagine a tough primary fight between Eliot Spitzer and John Edwards.
