She has proven to be a capable Senator for New York.
Really? Are you referring to the totally failed, money-wasting exercise on upstate NY revitalization? Or were you referring to her support and vote for the war in Iraq? Or were you referring to all of those other great pieces of legislation she sponsored and saw through ... oh, right, there really weren't any.
Her time as Secretary of State is certainly something she should be proud of.
Why? Because her phony "reset" stunt with Russia worked out so well? Check with the people in Crimea and throughout Ukraine on that one perhaps. Or were you thinking of her proud handling of the affairs in Libya, where her championing of the use of force to topple the leader there, with essentially no further involvement, has resulted in chaos, death, and the insurgence of whole new ISIS and AQ-style franchises murdering people by the thousands? Yes! Really something to be proud of. Or were you thinking perhaps of her wise ability to so gracefully handle the situation in Syria, which has turned into a calamity for millions of dead and feeling refugees that are now swamping Europe and carrying radical jihadism with them? Yes, that was really a moment of pride, promising but never delivering on the support that the moderate anti-Assad segments of Syrian society needed, allowing the radicals to move in wholesale, followed by Russia and Iran. A real moment of pride, there.
I suppose what you really mean is that she can be proud that she leveraged her position as Secretary of State to get foreign governments to hand millions of dollars to her family business while she was in office, in exchange for better access to her while they had issues in front of the State Department. Yes, by her standards, she should definitely be proud of how wealthy she made her family while she held that public office. Way to go, Hillary!
