As Secretary of State, she'd be going all over on official US business, much of which would be expected to stay confidential. It's not possible to conduct all negotiations in the open. Some things need to stay secret, some for a while, some for a long time.
Such as the negotiations on the part of the Prince of Oman.
she has way more government experience
1) So did Palin (vs Obama) but that didn't stop the criticism there 2) Most of Hilary's experience is being the wife of Monica Lewinsky's ex-boyfriend 3) Finally, most good democrats cannot even find ONE accomplishment of Hilary, besides #2)
Given the choice between Hilary and Carly, I'd take Carly. Which isn't actually saying much. Personally, I can't stand either of them.
You do realize Hilary was Secretary of State right?
Aren't you glad you're not getting all the government you pay for now?
