Eddie asks a reasonable question.
Her "resume" is better than Obama's. They were each senator for only a few years, but she has AG experience in a state larger in population than Canada or Australia. And, she's been VP for almost 4 years so she has had an opportunity to watch how it works up close.
Clinton had more executive experience as a Governor. A bit more than GWB. But GWB was Gov of a much bigger state. And a border state.
In contrast, GHWB had congressional and executive experience (head of cia, UN ambassador, plus 8 years VP experience.
Reagan was a 2 term Governor of California.
Trump ran a small private company. (It was believed to be a lot bigger when he was elected, we've since learned it was like 25 people).
Being president is not a one person job. It's an administration. I look to how they make decisions, and who they surround themselves with. Then the policies.
Kamala had a rough start as VP. Was effective in her previous gigs. She seems to have learned from her previous experiences. She seems pretty disciplined so far. She has been involved in an effective presidency. (Yes, look at numbers, don't listen to pundits. GDP, unemployment, stock market all better, crime lowest in 50 years. USA had best inflation response in developed world and its now down to its 2%ish acceptable rate. Border under control now after a rough couple of years and GOP sabotaging their own plan. Look at the bi-partisan bills Biden got done despite fervent opposition).
Thus, being part of this administration should help her if she's elected. She's had access to good people who know what they're doing and know how government works. And, an admin with almost no scandals (like Obama. Trump like Nixon with indictments and convictions everywhere. Zero for Obama, same with Biden).
I think Peggy Noonan (conservative speechwriter for Reagan/Bush) said it best - although Harris' rallies have this Obama quality, the difference is Obama created a movement, whereas Harris was created by a movement. (Or something like that).
But, until you see them in the gig w 100% responsibility, you don't know.
