I think the reason he picked her is she appeals to moderates more than some of the other candidates.
That has always been the script anyway.
She consistently polled early and long for the most likely nominee - because aside from checking the other boxes she was supposed to be a moderate- by California standards I guess.
Except that pooped out. She didnt really get many votes in more moderate states, or in her home state either. She brings the package early on but it does not age well.
